Dear cisco community,

I am currently running a IPV4 ebgp neighbor via my current 10G pipe to my ISP.

we recently added IPV6 neighbor,

we noticed, that the IPV4 neighbor is still pretty stable, however, our IPV6 neighbor keeps flapping from 5-10mins.

we can not get a stable BGp connection we our IPV6 addressing.

I am using a cisco CRS. 4.1 version.

is this behavior related to my physical 10G pipe, or my router neighbor discovery (ND).

thanks
