Current we dump four kinds of data from BGP router.
DUMP_BGP_ROUTE (use BGP command
"dump bgp routes-mrt" to dump RIB tables)
Format of archive files
Note: it dumps all update (announcement & withdrawal ) and state change messages into one file in every 60 minutes.
For example, the filename will be like all.20030321.144534
The format of this file is MRTd binary format. You can use route_btoa i all.20030321.144534 command to interpret these information into readable text MRTd format described as below:
TIME: 03/21/03 14:46:54 TYPE: BGP4MP/MESSAGE/Keepalive FROM: 128.119.3.248 AS1249 TO: 128.119.85.173 AS65432 TIME: 03/21/03 14:47:04 TYPE: BGP4MP/MESSAGE/Update FROM: 128.119.3.248 AS1249 TO: 128.119.85.173 AS65432 WITHDRAW 134.75.19.0/24 TIME: 03/21/03 14:47:33 TYPE: BGP4MP/MESSAGE/Update FROM: 128.119.3.248 AS1249 TO: 128.119.85.173 AS65432 WITHDRAW 134.75.171.0/24 134.75.180.0/24 134.75.196.0/24
Or you can use route_btoa i m all.20030321.144534 command to get another text MRTd format described as below:

Note: the same as dump bgp all command, but it will only dump the update messages. It does not dump the state change information in the file.
The format and usage of this file is the same as that in "DUMP BGP ALL"
Note: it dumps all available routes in RIB-IN routing table into one file in every 2 hours. (It seems that there is no best path information in this file)
The format of this file is MRTd binary format. You can use route_btoa i routes.20030321.104534 command to interpret these information into readable text MRTd format described as below:TIME: 03/21/03 10:45:34 TYPE: TABLE_DUMP/INET VIEW: 0 SEQUENCE: 1 PREFIX: 4.17.88.0/21 FROM: 128.119.3.248 AS1249 ORIGINATED: 03/17/03 20:54:20 ORIGIN: IGP ASPATH: 1249 10578 11537 10886 6059 NEXT_HOP: 128.119.3.248 STATUS: 0x1 TIME: 03/21/03 10:45:34 TYPE: TABLE_DUMP/INET VIEW: 0 SEQUENCE: 2 PREFIX: 6.1.0.0/16 FROM: 128.119.3.248 AS1249 ORIGINATED: 03/13/03 09:27:20 ORIGIN: IGP ASPATH: 1249 10578 11537 7170 1455 NEXT_HOP: 128.119.3.248 STATUS: 0x1Or you can use route_btoa i m routes.20030321.104534 command to get another text MRTd format described as below:

In this part, we use script-program to login the BGP router, show current
routing table and record all routes into a file. It contains the best path in
routing table.
The filename looks like BgpEcsUmass.20030320.1000.1048172400
