Lab – Configuring Basic PPP with Authentication

ia - IS-IS inter area, * - candidate default, U - per-user static route

o - ODR, P - periodic downloaded static route, H - NHRP, l - LISP

+ - replicated route, % - next hop override

Gateway of last resort is 10.2.2.2 to network 0.0.0.0

O*E2 0.0.0.0/0 [110/1] via 10.2.2.2, 00:08:14, Serial0/0/1

10.0.0.0/8 is variably subnetted, 3 subnets, 2 masks

O 10.1.1.0/30 [110/128] via 10.2.2.2, 00:08:14, Serial0/0/1

O 192.168.1.0/24 [110/129] via 10.2.2.2, 00:08:14, Serial0/0/1

Step 5: Configure the PCs.

Assign IP addresses and default gateways to the PCs according to the Addressing Table.

Step 6: Verify end-to-end connectivity.

All devices should be able to ping other devices in the Topology. If not, troubleshoot until you can establish

end-to-end connectivity.

Note: It may be necessary to disable the PC firewall to ping between PCs.

Step 7: Save your configurations.

Part 2: Configure PPP Encapsulation

Step 1: Display the default serial encapsulation.

On the routers, issue show interfaces serial interface-id to display the current serial encapsulation.

Branch1# show interfaces s0/0/0

Serial0/0/0 is up, line protocol is up
