Ipv6 Default route bgp

[Juan Barco]

Hi,

I am reciving a default route on bgp over ipv6 by my service provider. I want to control to only recive the default route, but when I ask for full table I recived all the routes, I don't know how to control the prefix to only recived the default route, this is what I have (ios XR):

prefix-set IPv6

  ::/0 le 128

end-set

route-policy PERMIT_IPv6

  if destination in IPv6 then

    pass

  endif

end-policy

router bgp 279xx

vrf INTERNET

neighbor 2800:xxxx:x:x:x:x:x:x

remote-as 523xx

description eBGP GlobeNetIPV6

update-source Bundle-Ether4.663

address-family ipv6 unicast

route-policy PERMIT_IPv6 in

route-policy IPV6_OUT out

Sorry for my english.

Check your route policies if the ISP ip range is already filtered

Hi,

Did you do a soft refresh after applying the policy ?

Hello

Your prefix is saying allow all routes, but you say you want to allow just the default

try this:

prefix-set IPv6

  ::/0

end-set

dont forget to do a soft clear also?

pdriver answer is the right one, you are allowing all routes

prefix-set IPv6

  ::/0 le 128

end-set

it allows :: from mask 0 to mask 128, just remove the "le 128"
