Hi everyone:
I'm brand new to xorp & multicasting and would like some ideas on how to
test my xorp configuration. The configuration was gleaned from previous
xorp postings. I have attached a copy of the conf file below. Xorp is
running on ubuntu server 9.04.
Interface eth1 is the connection to the internet (aaa.bbb.220.194/30).
Interface eth2 is the connection to the internal net (aaa.bbb.118.0/24).
When I run ssmping from the xorp router, I get the unicast replies but
no multicast replies. Is this to be expected if there no multicast
clients joined in a group?
Any help would be appreciated, thanks
