Hi all, I've enabled 6PE on some of our rsp720-3cxl's (running SRE8) that carry full global routes, and it appears to have allocated a separate MPLS label for each IPv6 prefix in BGP (approx 16,000 of them). Consequently this is chewing up significantly more FIB space, as each (global) IPv6 prefix now uses 1 144-bit slot and 1 72-bit slot (so 3 of the 1M entries available).
Is this right? It seems very wasteful, given that in the IPv4 world I only have labels for my IGP routes and everything else is happy being sent towards their favourite default route with just a "loopback" label on it. Some of the Cisco documentation mentions an "aggregate" IPv6 label, which would make more sense. Is this available on 7600/6500? Thanks, -- Steve _______________________________________________ cisco-nsp mailing list [email protected] https://puck.nether.net/mailman/listinfo/cisco-nsp archive at http://puck.nether.net/pipermail/cisco-nsp/
