ok... you have a lot of work in front of you....
begin with the 8300 lsp that has the 5 g700 stack
run the installation wizard to change the addresses
you will come to a point on the installation wizard the lists the media gateways and has a picture of a wrench.... click on each one of these to configure the gateway addresses. You want to do this from the location of the 8300 to prevent loosing your connection to the 8300. You can do it remotely if you wait to change the 8300 address until after the rest of the gateways are configured. Remember, you have to keep the path over the network. you can configure all the gateways from this wizard and it's much easier than doing them individually if you never have.
be sure to change the node-name ip for the LSP
If you have never done this... Use the Wizard... Then go back and check each gateway with the show commands I gave you....
When you are in the p330 stack controller, you can session to each gateway. use this command
this it for gateway 2
for gateway 3 and so on ..
For an lsp, your MGC list should be entered lile this.
clan, clan, 8300 (Ip addresses)
set mgc list x.x.x.x, x.x.x.x, x.x.x.x
you should make sure your recovery settings are correct...
2 on the transition points will let you search 2 clans for 4 min and the allow the third entry (8300 ADDRESS) to take over....
When do you plan on doing this???
