show bgp advertised-routes in VRFs does not seem to find an existing neighbor

Has anybody seen this behavior in XR5.3.2 too? I have not found any listed bug so far. Any DDTS available?

RP/0/RSP0/CPU0:ASR9K-1#sh bgp vrf PRO_MGMT ipv4 unicast nei 10.41.251.6 advertised-routes

hi matthias, you are hitting

the headline may be a bit misleading, but if you check the RNE of that ddts, you'll see that it applies. It is fixed in 533.

RNE:
<B>Symptom:</B>
Few nbr commands are not working:

show bgp neighbor x.x.x.x advertise/receive route returns error
% Neighbor not found

show bgp policy neighbor x.x.x.x commands return error

<B>Conditions:</B>
This issue happens for the last neighbor shown under show bgp summary.  For example in show bgp summary if x.x.x.x is last entry, then if you issue  show bgp policy neighbor x.x.x.x <options>  the error will be seen.

<B>Workaround:</B>
1. Create a dummy neighbor with higher IP address so that it becomes the last entry under show bgp summary.

2. Execute these commands without neighbor option and filter the resulting output based on the neighbor. If there are too many number of routes advertised, then this will take some time to display. output.

<B>Further Problem Description:</B>

Hi Xander

Many thanks for the fast reply. I expected something like that, I will do the upgrade eventually.

Cheers,
