[c-nsp] Maximum number of OSPF instances in aVRF-liteenvironment

[Timothy Arnold]

Slightly off the topic.

Is there any advantages for using OSPF for PE-CE routing? Or is it down to what the customer wants? I assume that most operators will use BGP (or maybe EIGRP?)

Great news!

We focus mostly on l2vpn's, but it's good to know this
limitation no longer exists if we do get customers
insistent on OSPF for a PE-CE routing protocol.

I recall IS-IS had the same issue in IOS. Do the new train
revisions also include this fix?

We are on SRC1 (moving to SRC2).

Cheers,

Mark.
