Using the BCC
To start NAT synchronization on a router using default values for most
parameters:
1.
Enable NAT synchronization on the router.
2.
Specify at least one synchronization peer.
Enabling NAT Synchronization
You must configure an IP interface on the router before you can enable NAT
synchronization. To enable NAT synchronization, navigate to the global NAT
prompt (for example,
box; ip; nat
) and enter:
synch enabled
[
synch-router-id
<n.n.n.n> ]
n.n.n.n can be any integer and must be unique for each peer router in a
synchronized configuration. Enter the value in the dotted-decimal format of an IP
address. A router IP address can be used as the ID.
If you enable synchronization without entering a synchronized router ID, the
router automatically inserts the IP address of an existing router IP interface.
If you want to set a different synchronized router ID, navigate to the global NAT
prompt (for example,
box; ip; nat
) and enter:
synch-router-id
<n.n.n.n>
Adding NAT Synchronization Peers
To add a router to the list of synchronized peer routers, navigate to the global NAT
prompt (for example,
box; ip; nat
) and enter:
peer
<synch_router_id>
address
<address>
synch_router_id
is the unique ID assigned to the peer router.
address is the IP address of the interface that the peer router will use to make TCP
connections when sending or receiving address translations.
