IPv6 Routing Protocols
Most of the routing protocols I’ve already discussed have been upgraded for use in IPv6 networks.
Also, many of the functions and configurations you’ve already learned will be used in almost the
same way as they’re used now. Knowing that broadcasts have been eliminated in IPv6, it follows
that any protocols that use entirely broadcast traffic will go the way of the dodo—but unlike the
dodo, it’ll be good to say goodbye to these bandwidth-hogging, performance-annihilating little
gremlins!
The routing protocols you’ll still use in v6 have gotten a new name and a facelift. I’ll talk
about a few of them now.
First on the list is
RIPng
(next generation). If you’ve been in IT for a while, you know
that RIP has worked well on smaller networks, which happens to be the reason it didn’t get
whacked and will still be around in IPv6. And you still have EIGRPv6 because it already had
protocol-dependent modules, and all you have to do was add a new one to it for the IPv6 protocol.
Rounding out the group of protocol survivors is OSPFv3—that’s not a typo; it really is
v3. OSPF for IPv4 was actually v2, so when it got its upgrade to IPv6, it became OSPFv3.
