I am trying to have a very simple BGP ORF scenario but somehow receiver side
always report malformed prefixes.
Could you help me on that?


Customer Configuration:

router bgp 60001
bgp router-id 10.1.1.3
network 31.0.0.0/8
network 32.0.0.0/8
network 33.0.0.0/8
network 34.0.0.0/8
!
neighbor 10.1.1.2 remote-as 60000
neighbor 10.1.1.2 strict-capability-match
neighbor 10.1.1.2 capability orf prefix-list send
neighbor 10.1.1.2 prefix-list PREFIXORFA in
!
ip prefix-list PREFIXORFA seq 5 permit 21.0.0.0/8
ip prefix-list PREFIXORFA seq 10 permit 22.0.0.0/8

Provider Configuration:

router bgp 60000
bgp router-id 10.1.1.2
network 21.0.0.0/8
network 22.0.0.0/8
network 23.0.0.0/8
network 24.0.0.0/8
!
neighbor 10.1.1.3 remote-as 60001
neighbor 10.1.1.3 strict-capability-match
neighbor 10.1.1.3 capability orf prefix-list receive
