Confirming Multilink PPP Configuration for the B1 Channel
Perform the two verification procedures in this section to verify that multilink
PPP is configured on the ISDN B1 channel.
For the first verification procedure, perform these steps:
Step 1 From the privileged EXEC mode, confirm that the ISDN is connected to the
remote site by entering the ping command, followed by the IP address of the
central-site router:
Router# ping 192.168.37.40
Step 2 Enter the show ppp multilink command.
Step 3 Confirm that the “Master link is Virtual-Access1” message appears in the
command output.
Router# show ppp multilink
Bundle HQ, 1 member, Master link is Virtual-Access1
Dialer Interface is BRI0
0 lost fragments, 0 reordered, 0 unassigned, sequence 0x0/0x0
rcvd/sent
0 discarded, 0 lost received, 1/255 load
Member Link: 1
BRI0:1
Step 4 If you do not see the message in the output, do one or both of the following:
• Confirm that multilink PPP is configured on the central-site router that you
are connecting to.
• If multilink PPP is configured on the central-site router, use the
show interface command as described in the second verification procedure.
Step 5 To continue configuration, reenter global configuration mode.
