Practice Scenario 2 Suggested Solution
Although your choice of dial-peer tags might vary, the following offers a suggested solution
to Practice Scenario 2:
R1:
dial-peer voice 3111 voip
destination-pattern 3111
Session target ipv4:10.1.1.2
dial-peer voice 3112 voip
destination-pattern 3112
Session target ipv4:10.1.1.2
dial-peer voice 3113 voip
destination-pattern 3113
Session target ipv4:10.1.1.2
R2:
dial-peer voice 2222 voip
destination-pattern 2222
Session target ipv4:10.1.1.1
From this practice scenario, notice how configuration intensive it would be for an administrator
to configure a dial peer for each phone number in a VoIP network. Next, consider
how wildcards can be used with the destination-pattern command to allow a single dial
peer to point to multiple phone numbers.
