Subject: [PATCH 2/4] bgpd: Show the real next-hop address in addition to |
|
|
|
hostname in `show bgp` |
|
|
|
|
|
|
|
It's hard to cope with cases when next-hop is changed/unchanged or |
|
|
|
peers are non-direct. |
|
|
|
|
|
|
|
It would be better to show the hostname and nexthop IP address (both) |
|
|
|
under `show bgp` to quickly identify the source and the real next-hop |
|
|
|
of the route. |
|
|
|
|
|
|
|
If `bgp default show-nexthop-hostname` is toggled the output looks like: |
|
|
|
``` |
|
|
|
spine1-debian-9# show bgp |
|
|
|
BGP table version is 1, local router ID is 2.2.2.2, vrf id 0 |
|
|
|
Default local pref 100, local AS 65002 |
|
|
|
Status codes: s suppressed, d damped, h history, * valid, > best, = multipath, |
|
|
|
i internal, r RIB-failure, S Stale, R Removed |
|
|
|
