[c-nsp] Strange IP address

[Harold Ritter (hritter)]

Hi,

There¹s at least two alternatives you can use. You either need to use a
route-map under AF ipv4 to change the next-hop explicitly for the ipv4
prefixes or you can run a separate session for v4 ad v6 prefixes
respectively. The latter is generally recommended.

Regards

Harold
