Hi,
I have a problem in R1 he doesn’t create any neighbor relationship:
These are the logs:
*Jul 9 17:58:35.187: BGP: ses global 3.3.3.3 (0x655EF9CC:0) act Reset (Active open failed).
*Jul 9 17:58:35.199: BGP: 3.3.3.3 active went from Active to Idle
*Jul 9 17:58:35.199: BGP: nbr global 3.3.3.3 Active open failed - open timer running
*Jul 9 17:58:35.203: BGP: nbr global 3.3.3.3 Active open failed - open timer running
Example for R3 but it’s the same for R2 and R4:
router bgp 1
bgp log-neighbor-changes
neighbor R2_R3_R4 peer-group
neighbor R2_R3_R4 ebgp-multihop 2
neighbor R2_R3_R4 update-source Loopback0
neighbor 2.2.2.2 remote-as 2
neighbor 2.2.2.2 peer-group R2_R3_R4
neighbor 3.3.3.3 remote-as 3
neighbor 3.3.3.3 peer-group R2_R3_R4
neighbor 4.4.4.4 remote-as 4
neighbor 4.4.4.4 peer-group R2_R3_R4
