Re: MPLS TE with OSPF

I remember that there was a bug with the OSPF network type non-Broadcast
Change the OSPF to point-point...ect , and check it out.

CSCsh42565 Bug Details
*TE tunnel* does not come up on ospf *non-broadcast network type
*
*Symptoms:* Traffic engineering (TE) tunnels go down when an intermediate
 link has the ip ospf network non-broadcast command enabled.

*Conditions:* This symptom is observed in an OSPF network over TE tunnels
 that are established on non-broadcast links.

*My Workaround*: Do not use non-broadcast links. Rather, use another OSPF
network
type. If this is not an option, there is no workaround.

NO the workaround is ip* ospf network point-to-multipoint non-broadcast*
