IMHO, any serious network operator using OSPF or BGP should
have already deployed the techniques below (as applicable):
OSPF with Keyed MD5 Authentication
BGP-4 with the Keyed MD5 Authentication extension
as a TCP option.
WRT ISIS, lack of a CLNP infrastructure limits the ability of
outsiders to attack a network. Nonetheless, ISIS should probably
also get some kind of cryptographic authentication extension.
