hi, I meet a problem of ibgp.
Term-----R4-----R1-----R2-----R5-----R3
| | | | |
Net1 Net2 Net3 Net4 Net5
there R1 belonging one AS,R2/R3/R4/R5 belonging one AS,R6 belonging one AS, R2/
R3/R4/R5 configued with IBGP full meshed and no sync enabled, but I met a probl
em R2 cant be peering with R5 and the others can do well, and then the routing
table of R5 has the Net2 entry but every 0ne minute later is disapearing.
The configuration is the following:
