[c-nsp] Weird rACL entry - interface to interface OSPF packets

[Michael K. Smith - Adhost]

Hello All:

We've been running rACL's for about 3 weeks with no issues.  This
morning, we started seeing blocks of OSPF messages going directly from
one directly connected SRP interface to another.  Our original rACL
entries permitted OSPF traffic to and from 224.0.0.5 and .6 and that has
been in place since the beginning.

Can anyone shed light on why there would be interface to interface OSPF
communication not going to the well-known multicast addresses?  Is this
to be expected or do I have configuration issues?  I've included log and
config snippets below.

Regards,

Mike
