Summary: Removing bgp peer-group with active peers
Product: Quagga
Version: CVS

2 neighbors were configured as part of a bgp route-server peer-group, both
neighbors had sessions established. Peer-group was removed from the
configuration, causing bgp neighbor statements to disappear from configuration.
Neighbor statements were re-added, bgpd crashed.


Configuration BEFORE:

router bgp 65188
bgp router-id 192.168.1.188
neighbor MLPA peer-group
neighbor MLPA route-server-client
neighbor MLPA route-map MLPA in
neighbor MLPA route-map MLPA export
neighbor 192.168.1.184 remote-as 65184
neighbor 192.168.1.184 peer-group MLPA
neighbor 192.168.1.195 remote-as 65195
neighbor 192.168.1.195 peer-group MLPA


Commands issued:

no neighbor MLPA (neighbors 192.168.1.184 and 192.168.1.195 disappear)
neighbor 192.168.1.184 remote-as 65184
neighbor 192.168.1.195 remote-as 65195
neighbor 192.168.1.195 route-server-client (bgpd crashes)
