Dear wonderful team,
I have a cisco 7200 as src Mcast 239.16.1.1. it is running sparse mode with SRX 340. I have setup destination nat on ge-0/0/1 to nat mcast from 239.16.1.1 to 239.141.1.10.
destination nat on SRX:
set security nat destination pool NAT_Mcast address 239.141.1.10/32
set security nat destination rule-set NAT_Mcast_1 from interface ge-0/0/1.0
set security nat destination rule-set NAT_Mcast_1 rule R1 match destination-address 239.16.1.1/32
set security nat destination rule-set NAT_Mcast_1 rule R1 then destination-nat pool NAT_Mcast
with sparse mode, it does not nat and does not NAT. when I switch to dense-mode, it works as expected.
PIM neighbor is up on both side (SRX and Src Mcast)
rp on SRX:
set protocols pim rp static address 192.168.0.1 group-ranges 239.141.1.10/32
set protocols pim rp static address 192.168.1.1 group-ranges 239.16.1.1/32
rp on src Mcast cisco:
ip pim rp-add 192.168.1.1 239.16.1.1
I changed the RP address for 239.16.1.1 to 192.168.1.2, but no luck
however, when I replace src Mcast cisco router with a PC, it nats properly.
unicast routing is good.
SRX interface:
set interfaces ge-0/0/1 unit 0 family inet address 192.168.1.1/24
set protocols ospf area 0.0.0.0 interface ge-0/0/1.0
set protocols igmp interface ge-0/0/1.0 static group 239.16.1.1
set protocols pim interface ge-0/0/1.0 mode sparse
Cisco interface:
interface FastEthernet0/0
ip address 192.168.1.2 255.255.255.0
ip pim sparse-mode
ip igmp join-group 239.16.1.1
duplex half
any idea why sparse mode does make SRX not to nat?
thanks in advance
