[rbak-nsp] OSPF between FreeBSD and SE100

[Sridhar]

hi Marcin,

what is the MTU of the SE100 interface connecting it to the FreeBSD box?

1. Please provide the output of "sh ip interface brief" from the SE100
(this shows MTU)
2. Please provide the output of "debug ospf all" (I'm not sure what
ospf debugs you enabled)

thanks
sridhar
