[6bone] Re: routing concern

[Robert J. Rockell]

Fixed.

Explanation:  We redistribute static (with route-map) in order to aggregate,
so we keep Null0 static routes on each core router, to make sure that we
inject the aggregate.   When building new routers, at some point recently
one of the IPv6 team here must have fat-fingered the mask for our 6bone
delegation, and applied it to our ARIN delegation.  This is now corrected:

sl-bb1v6-rly#sho bgp ipv 2001:400::/24
BGP routing table entry for 2001:400::/24, version 56
Paths: (2 available, best #2)
  Advertised to non peer-group peers:
  2001:440:6175:3::1 3FFE:900:0:1C::1 3FFE:A00:2:2::9 3FFE:B00:C18::E
  3FFE:C00:8023:29::1 3FFE:1CFF:0:EC::1 3FFE:28FF:FFFF:1::114
3FFE:2900:1::2D
  3FFE:2900:1:4::2 3FFE:2900:1:5::2 3FFE:2900:1:9::2 3FFE:2900:1:F::2
  3FFE:2900:1:10::2 3FFE:2900:5:5::2 3FFE:2900:A:1::2 3FFE:2900:A:4::2
  3FFE:2900:A:6::2 3FFE:2900:A:7::2 3FFE:2900:A:A::2 3FFE:2900:A:B::2

  3FFE:2900:C:5::2 3FFE:2900:C:7::2 3FFE:2900:C:C::2 3FFE:2900:C:F::2
  3FFE:2900:D:6::2 3FFE:2900:D:E::2 3FFE:2900:E:2::2 3FFE:2900:E:3::2
  3FFE:2900:E:C::2 3FFE:2900:F:C::2 3FFE:2900:F:E::2 3FFE:2D00:1::F
3FFE:3600::3
  3FFE:8000:FFFF:29::1
  Local
    2001:440:6175:4::1 (metric 63) from 2001:440:6175:4::1 (144.228.240.145)
     Origin IGP, localpref 100, valid, internal
  Local
    2001:440:6175:2::1 (metric 20) from 2001:440:6175:2::1 (208.11.232.40)
      Origin IGP, localpref 100, valid, internal, best

and null routes removed:

sl-bb1v6-rly#sho bgp ipv 2001:400::/24
BGP routing table entry for 2001:400::/24, version 3963
Paths: (0 available, no best path)
Flag: 0x820
  Not advertised to any peer


apologies for attempted assimilation of other people's ARIN delegations :)

We'll tighten 'er down a bit today.

Bill, if you aren't getting enough routes from us, send me personal mail,
and we'll fix for you.
