[Date Prev][Date Next][Thread Prev][Thread Next][Date Index][Thread Index] Re: [FW-1] Cluster XL FP3 - Mulicast or Broadcast?
Title: Message ClusterXL works by mapping an unicast IP address (Cluster IP address) to
a multicast IP address.
As
it's not exactly RFC like, Cisco switch and router seem to have problem
with this.
Check
in the ARP table of the next hop router if you've got an entry
associating the IP address of the cluster with the MAC multicast address. If
not, add one static entry.
Check
in the CAM table of the switch if you could see the virtual multicast MAC
addres. If not, add it statically on the interfaces on wich you've plugged the
gateway.
This
should help solving the problem.
Additionnaly, on complex LAN architecture, you could put all this in a
seperate VLAN. We have tryed also to disable IGMP Snooping, on the switch. The
purpose of this test was that the switch handle the multicast traffic as
broadcast. We got 2 Cico in HSRP mode, and what we see is that it don't work
too. The packets goes from one cisco to the other (real IP, not HSRP
IP).
