Hi Matt,
I used to run VPLS multihoming in my network, I used LDP based VPLS between the MX routers, not BGP based VPLS, that based on our tests LDP based VPLS convergence time (MAC flush) was much faster than BGP based. The loop prevention mechanism I used was vstp, that it gives the ability to control the blocking per vlan not the whole physical link; I used to run vstp on MX using layer2 control routing instance. Hope it is helpful. Mohammad Salbad _______________________________________________ juniper-nsp mailing list [email protected] https://puck.nether.net/mailman/listinfo/juniper-nsp
