Hi Randy,

Thanks - Ill keep them as broadcast for the time being....both routers have a number of other adjacencies, so Id prefer to not "break" them as it is in production.

portchan on R1+R2 are clean+full dup both ends....they also have other existing (working) links with ospf running without issue(Plus numerous client ethernet tails all also working fine)
R1 hasportchan subint to "R3" (OSPF Working fine for years) GigEth subint to "R3" (OSPF Working fine for years)Fasteth int to "R2" (OSPF working fine for years)portchan subint to "R2" (OSPF not working as discussed)
(R1 portchan is dual trunk to 3750 stack, which then has carrier hand-offs as trunk ports(Tails handed off to us as vlans))
R2 hasportchan subint to "R1" (OSPF Working fine for years)portchan subint to "R1" (OSPF not working as discussed)portchan subint to "R3" (OSPF working fine for years)
(R2 portchan is dual trunk to 3560, which then has carrier hand-offs as trunk ports(Tails handed off to us as vlans))
