It is. The problem is that our routing table support only a single route for a prefix (yep, there is RADIX_MPATH, but it serves other needs). Thus, every time we add or delete a prefix we need to do a lot of sanity checking: running through interfaces list, seek for other origin for this prefix, etc. All suggested patches do this, and from my viewpoint these are crutches.

Hmmm... how have you managed to have a next hop address of 10.7.26.2 on your vlan74 interface, when the local network appears to be 10.1.26.0/23 ? What's the route to 10.7.26.2 -- presumably this is also accessible on vlan74 ? It certainly seems odd that your routes have disappeared, but I'm wondering if they were culled from the routing table because the system thought they weren't logically connected to the local system?
