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

Cucumber

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)
