День добрый
Пытаюсь поднять multicast routing в сети.
PC (10.1.1.2/24) --- (10.1.1.1/24) ciscoA (10.10.10.1/24) ------
(10.10.10.200/24) ciscoB (10.2.2.1/24) --- (10.2.2.2/24) PC
Конфиги:

Решил проверить видит ли писюк ближайшую циску через multicast:
skiv@skiv$mtrace 10.10.10.1 224.1.1.1
Mtrace from 10.10.10.1 to 10.1.1.2 via group 224.1.1.1
Querying full reverse path... * switching to hop-by-hop:
0 ? (10.1.1.2)
-1 * * *
-2 * * *
-3 * * *
-4 * * * ...giving up
Timed out receiving responses
Perhaps no local router has a route for source 10.10.10.1
в таблице multicast есть запись
(*, 224.0.1.32), 00:01:52/00:02:06, RP 10.10.10.1, flags: SJC
Incoming interface: Null, RPF nbr 0.0.0.0
Outgoing interface list:
GigabitEthernet0/0.1, Forward/Sparse-Dense, 00:01:52/00:02:06
на connected сети писюк циску тоже не видит
skiv@skiv$mtrace 10.1.1.1 224.1.1.1
Mtrace from 10.1.1.1 to 10.1.1.2 via group 224.1.1.1
mtrace: Source & receiver appear to be directly connected
Querying full reverse path... * switching to hop-by-hop:
0 ? (10.1.1.2)
-1 * * *
-2 * * *
-3 * * *
-4 * * * ...giving up
Timed out receiving responses
Perhaps no local router has a route for source 10.1.1.1
tcpdump'ом запросы видно, ответов от циски нет. Прописывание
интерфейса в сторону писюка в ip igmp join-group 224.1.1.1 ничего не дает,
те же звезды.
Где я неправ?
ifconfig vx0
vx0: flags=8843<UP,BROADCAST,RUNNING,SIMPLEX,MULTICAST> mtu 1500
inet 10.1.1.2 netmask 0xffffff00 broadcast 10.1.1.255
ether 00:a0:24:0b:0b:4d
Router#sh ip pim rp mapping

This system is an RP (Auto-RP)
