I would say common practice - if you're using VRF's in a multivendor environment with draft-rosen for instance, I believe you MUST use the same IP address in the lo0.x interface, as the "other" vendor expects the lo0.0 address (which the Juniper won't send). Of course all Juniper network won't

Does anyone see a problem or have any experiences with using the same loopback unit 0 IP addresses for other loopback unit in VRFs? Is this a common practice? For example, loopback unit 0 is 172.16.1.1/32 and lives in inet.0. loopback 425 is 172.16.1.1/32 lives in a vrf. -Chip ___
