The router static router static is a keyword: locating to static addresses
address-family ipv4 unicast
10.191.254.0/24 GigabitEthernet 0/4/0/261.148.56.42
61.50.217.32/28 GigabitEthernet 0/2/1/561.148.57.134
61.50.247.0/25 GigabitEthernet 0/4/1/961.148.167.60
The vrf VIP vrf is a keyword for positioning the address of the strip vrf

“125.35.7.64/27 GigabitEthernet0/5/1/8.261 61.148.56.226”
For the obtained VPN address, the second field behind is the port corresponding to the address, and the third field is the next hop of the IP address.
(1) Locating router static in the configuration file, reading all the IP address fields contained in vrf below (not the routing address below vrf is not of interest), encountering "! "indicates that a single vrf contains complete reading of the IP address segment, and records all the address segments inside vrf in turn, and" Gigabit Ethernet 0/5/1/8.261.148.56.226 "behind vrf is vrf name.

display bgp routing-table peer 43.254.0.254 received-routes
the behavioral command line, "43.254.0.254" is the peer address (each peer address fetched above executes this command)
Taking the peer address 43.254.0.254 as an example, the result is as follows:
8. analyzing and comparing the collected address information
Intra-domain routing is all address information for the universe. And comparing various types of subsequently acquired address information with the intra-domain route according to a self-defined sequence, marking the matched address information, and acquiring corresponding IP address use classification.
The configuration rules are as follows in table 1:
TABLE 1
Configuration data:
insert into AddrTabCompCfg(TABLENAME,IPTYPE,ISCOMVRF,SEQ)
values('VpnUserAddrBJLT','V','1',1)；
insert into AddrTabCompCfg(TABLENAME,IPTYPE,ISCOMVRF,SEQ)
values('BgpUserAddrBJLT','B','0',2)；
insert into AddrTabCompCfg(TABLENAME,IPTYPE,ISCOMVRF,SEQ)
values('ZiJinUserAddrBJLT','Z','0',3)；
insert into AddrTabCompCfg(TABLENAME,IPTYPE,ISCOMVRF,SEQ)
values('ConvergeAddrBJLT','C','0',4)；
insert into AddrTabCompCfg(TABLENAME,IPTYPE,ISCOMVRF,SEQ)
values('BlackHoleAddrBJLT','H','0',5)；
insert into AddrTabCompCfg(TABLENAME,IPTYPE,ISCOMVRF,SEQ)
values('BasDevAddrBJLT','D','0',6)；
insert into AddrTabCompCfg(TABLENAME,IPTYPE,ISCOMVRF,SEQ)
values('BasAddrPoolBJLT','P','0',7)；
the specific algorithm is as follows:
the first step is as follows: matching the intra-domain route with various addresses in the configuration table according to the sequence of AddrTabCompCfg.seq from small to large, and marking the type.
According to the sequence of seq, processing the records with the smallest seq value in the configuration rule table one by one
And finding out the acquisition data table corresponding to the ip classification according to the table name.
If ISCOMVRF =0, the network field in the acquisition data table is matched with the network field of the in-domain routing table InDomainRouAddr. And assigning the iptype to the iptype value in the InDomainRouAddr table of the address segments with completely equal network, namely marking the corresponding ip classification mark. If the matching can not be carried out, a record is added to the routing table in the domain, and the iptype is marked as the iptype of the current configuration table.
If ISCOMVRF =1, the network field & & vrf in the acquisition data table is matched with the network & & vrf field of the in-domain routing table InDomainRouAddr. Assigning the iptype to the iptype value in the InDomainRouAddr table according to the address fields with completely equal field values, namely, marking the corresponding ip classification mark. If the configuration table can not be completely matched, a record is added to the routing table in the domain, and the iptype is marked as the iptype of the current configuration table.
Note: the order of the configuration table seq is very important and needs to put more detailed IP classification in front of matching. The matching sequence is a VPN routing address, a BGP routing address, a non-BGP or VPN accessed purple gold private line service address, a relay address, a black hole routing address, a Bras equipment address and a Bras address pool address.
The second step is that: after the initial classification is completed, the service data needs to be supplemented to the existing classified address according to the needs. And performing secondary matching on the address of the unmatched type.
And if the iptype is a BGP (B) or VPN (V) routing address, comparing the network with the ipaddr of the service address table, and if the iptype is the IDC and the common private line is consistent, changing the iptype into the IDC (A) or the private line (L) according to the service type of the service address table. Matching the network with ZijinUserAddrBJLT table network, if the network is consistent with the ZijinUserAddrBJLT table network, the network is the Zijinprivate line service address accessed by VPN or BGP, and the iptype is changed into the Zijinprivate line (Z).
And comparing the address with the ipaddr of the service address table if the iptype is empty, and if the iptype is equal to the empty address, changing the iptype into IDC (A) or special line (L) according to the IDC and the common special line of the service address table. This part is the traffic address of the non-BGP and VPN accesses.
Comparing the address with ipaddr in the relay address table if the iptype is empty, if the address is equal to the ipaddr, the address is the relay address, and the iptype is marked as I
9. Providing comprehensive inquiry function by dividing IP address into use types
Fill in the IP address range (single IP address, or start address-end address, or IP/mask bit number if multiple, please separate with english comma), click query.
IDC private line address: conditional IP, private line number, device name, device IP, port description.
BGP access special line: conditional IP, private line number, device name, device IP, port description.
The out-of-domain addresses (addresses that cannot be matched in the InDomainRouAddr table) are shown in Table 2 below:
TABLE 2
| IP address | Address type | AS-path |
| X.x.x.x | Out-of-domain addresses | 483765035 |

Relay address (inpomain rouaddr. Iptype = I) is as follows table 4:
TABLE 4
| IP address | Address type | Device name | Equipment IP | Port name | Port description | Intra-domain address types |
| Relay address |

and when the input condition IP is in the InDomainRouAddr which is matched with the InDomainRouAddr table and is associated with InDomainRouAddr. Iptype = D/X, indicating that the condition IP is the BRAS/broadband access device address, and entering the display column.
