Configuration of Router 2
To create the dial backup configuration in Figure B-5
on page B-24, configure
router 2 as follows:
1.
Enter configuration mode:
bcc>
config
2.
Configure a leased synchronous interface on an ASN with PPP on serial
interface slot 3, module 3, connector 1.
stack#
serial 3/3/1
serial/3/3/1#
ppp
ppp/3/3/1#
ip 129.122.3.2/255.255.255.0
ip/192.122.3.2/255.255.255.0#
stack
3.
Create a dial object for serial interface slot 2, module 1, connector 1. PPP
is the default protocol.
stack#
serial 2/1/1
serial/2/1/1#
dial
dial/serial/2/1/1#
stack
4.
Create a backup pool with pool ID 24, then create a backup line on the
serial interface you created in step 3. Add this line to the pool.
stack#
backup-pool 24
backup-pool/24#
backup-line serial/2/1/1
5.
Configure a backup circuit for the leased circuit ppp/3/3/1. Also, set the
backup-mode
parameter to receiver.
backup-line/24/serial/2/1/1#
stack; serial 3/3/1; ppp
ppp/3/3/1#
backup-circuit pool-id 24 backup-mode receiver
This circuit uses backup lines configured in the backup pool 24. The
backup-mode
parameter is set to receiver, the other router’s backup-mode
must be set to initiator for proper operation.
6.
Configure a caller resolution table entry so when this router receives a
call from router 1, it can verify router 1’s identity.
backup-circuit/24/3/3/1#
caller-resolution caller-name bln secret west
caller-resolution/bln#
back
7.
Accept the default circuit schedule.
