[c-nsp] igp / ebgp problem ipv6

[Paul Stewart]

Hi there.

 

We have our first IPv6 block advertising to the world (for quite a while
now) and have started to actually route some small blocks of it internally
via OSPF.  Our /32 is advertised via eBGP no problem and the world can see
it..

 

Internally, we have a series of /128 loopbacks, /126 point to points, and a
/64 block setup for some servers.  Obviously all small chunks of the /32
assignment.

 

My problem is that the world can reach our border routers but traffic will
not route beyond the border.  Internally, we can route traffic no problem..

 

Config looks basically like this:

 

router bgp 00000

 

address-family ipv6

  no synchronization

  network 0000:0000::/32

 

ipv6 route 0000:0000::/32 Null0

ipv6 router ospf 1

 log-adjacency-changes

 default-information originate

 redistribute connected

 

 

Then the applicable nei statements and ospf for IPv6 is enabled on certain
interfaces... Could post more config but hopefully this triggers someone
with an answer ;)  The block is showing fine as a /32 to the world and
internally everything is reachable via ospf.. I know it has something to do
with the small subnets inside of the /32 but drawing a blank..

 

Thanks ;)
