We have a requirement to send data via multicast from source to destination
it only has to go through one MRouter which is a 3750G configured with PIMSM
All the router does is pick up packets from the source which is directly off one interface and statically route them down the appropriate interface to the receiver.
The data is a dump of files which is done periodically and we cannot lose any of the packets.
What happens is if they don't do a dump for a while the (S,G) times out. Then it has to be created again at the beginning of every dump.
During that time we lose some of the first packets.
Is there any way to get around this by statically creating (S,G) states or any other options?
I know we can increase the sg-expiry-timeout but eventually it will expire.
Can the expiry-timeout be set to never ?
