Multicast adress routing protocol

fillthy

Hi, I know OSPF uses 224.0.0.5 muticast, what other routing protocols use muticast addresses?
Thanks

EIGRP uses 224.0.0.10

But note that OSPF also uses 224.0.0.6

DR's and BDR's listen for 224.0.0.6 multicast packets and non-DR's listen for 224.0.0.5...

OSPF uses Unicast when no DR is needed.

Cucumber

And RIPv2 uses 224.0.0.9

STP multicasts BPDU's, but thats not a routing protocol.

Technically ISIS uses multicast, but uses CLNS addresses rather than IP addresses :P

I think STP and ISIS both use Layer2 multicasts:
STP uses 0180.C200.0000,
ISIS uses :
For Level 1 PDUs: 0180.C200.0014 is used (AllL1IS)
For Level 2 PDUs: 0180.C200.0015 is used (AllL2IS)
