Can't find any reason why bmp config on IOS-XR is not sending anything
to server
bmp server 1
bmp server 1 host 10.y.x.z port 1790
bmp server 1 vrf MYVRF
bmp server 1 description blabla-pmbmpd
bmp server 1 update-source LoopbackA
bmp server 1 flapping-delay 3600
bmp server 1 initial-delay 60
bmp server 1 stats-reporting-period 120
bmp server 1 initial-refresh delay 120
=> works
router bgp 65534 neighbor 192.168.2.1 bmp-activate server 1
=> not working
router bgp 65534 neighbor 2001:dead::beef bmp-activate server 1
Seems related to IOS-XR behavior but can't explain why as I received no
IPv6 BMP dump on IPv4 10.x.y.z
Did someone already worked on it ?
