The primary purpose of IP routing attacks are to disrupt/corrupt router peering or routing information in order to cause denial of service attack or provide help to other type of attacks like DNS cache poisoning etc.

In an IPv6 environment the operators of the network can face similar attacks against the routing infrastructure. However in an IPv6 environment the network designers should be aware of certain idiosyncrasies of IPv6 routing.

In the cases of BGP, IS-IS and EIGRP the security algorithms of the routing protocol remains the same: keyed MD5 digest. So in these cases the same protection for the routing protocol should be used.

By contrast, in the case of OSPFv3 [RFC2740] and RIPng [RFC2080] the routing protocol has been adapted to IPv6 and relies on the IPSec protocol. So if you are using OSPFv3 or RIPng for routing you should also configure IPSec to protect these routing protocols.

The other types of attacks against the routing infrastructure as mentioned are very similar to IPv4 routing infrastructure attacks, therefore similar countermeasures should be implemented: e.g. infrastructure protection, limiting access to the router, SSH authentication etc.
