O - OSPF, I - IS-IS, B - BGP, E - EIGRP, N - NHRP,
T - Table, v - VNC, V - VNC-Direct, A - Babel, D - SHARP,
F - PBR,
> - selected route, * - FIB route

AD: neighbors Seattle: BGP Neighbor Address: 7.7.7.7
Neighbor AS Number: 100 Local Address: Routing + Routing Interface: rtg-int-bos Time-to-live Value: 5 ( for BGP Multihop Settings ) Address Families. Select bgp:ipv4-unicast. ( + Router As Next Hop: True )
Dallas: BGP Neighbor Address: 8.8.8.8
b. Neighbor AS Number: 200 Local Address: Routing + Routing Interface: rtg-int-bos Time-to-live Value: 5 ( for BGP Multihop Settings ) Address Families. Select bgp:ipv4-unicast. ( + Router As Next Hop: True ) |
