My argument against that design is simple: spanning-tree. Why expose yourself to one more thing that can, and sometimes does, malfunction? We live in a world where multi-vendor L3VPN works pretty good, but spanning-tree is apparently really hard to figure out, especially for some vendors who are particularly good at routing and not so experienced at Ethernet bridging. There are plenty of other good reasons not to do a big vlan for all the routers in that area, but the reason above should be good enough for anyone. -- Jeff S Wheeler <[email protected]> Sr Network Operator / Innovative Network Concepts _______________________________________________ juniper-nsp mailing list [email protected] https://puck.nether.net/mailman/listinfo/juniper-nsp
