It was to be the default, but currently not compatible w/vpls. http://www.juniper.net/techpubs/en_US/junos9.6/information-products/topic-collections/config-guide-routing/routing-enabling-indirect-next-hops.html
IIRC, a fix in the works to except vpls so the rest of the system can use INHs. As of now I believe it fails the commit.

We've been running it globally for quite a while, don't think we've ever seen a problem with it. I'm sure it will become a default eventually, like distributed ppm offloading which IIRC was introduced at around the same time. -- Richard A Steenbergen <r...@e-gerbil.net> http://www.e-gerbil.net/ras GPG Key ID: 0xF8B12CBC (7535 7F59 8204 ED1F CC1C 53AF 4C41 5ECA F8B1 2CBC) _______________________________________________ juniper-nsp mailing list juniper-nsp@puck.nether.net https://puck.nether.net/mailman/listinfo/juniper-nsp _______________________________________________ juniper-nsp mailing list juniper-nsp@puck.nether.net https://puck.nether.net/mailman/listinfo/juniper-nsp
