Inverse arp is disabled everywhere and I confirmed that I only have static
entries in the FR map statements. I am running pim-dense on the lan
interfaces, pim-sparse and pim-nbma on the FR interfaces with R1 as the rp.
For example on r3 (one of the spokes):
r3#sh frame map
Serial0 (up): ip 157.20.100.1 dlci 301(0x12D,0x48D0), static,
broadcast,
CISCO, status defined, active
Serial0 (up): ip 157.20.100.2 dlci 301(0x12D,0x48D0), static,
broadcast,
CISCO, status defined, active
r3#ping 224.10.10.2
Type escape sequence to abort.
Sending 1, 100-byte ICMP Echos to 224.10.10.2, timeout is 2 seconds:
