Learning by Doing: CISCO Certified Network ... - SCN Research

Here we can see a problem with our ISDN connection. Unlike the MERGE box
we need to include service profile identifiers, ppp and authentication.
smarts(config-if)#isdn spid1 51055512340001 5551234
smarts(config-if)#isdn spid2 51055512350001 5551235
smarts(config-if)#enc ppp
smarts(config-if)#ppp authentication chap
smarts(config)#username kissane password 0 cisco
smarts(config)#ip host kissane 192.168.1.2
kissane(config-if)#isdn spid1 51055540000001 5554000
kissane(config-if)#isdn spid2 51055540010001 5554001
kissane(config-if)#enc ppp
kissane(config-if)#ppp authentication chap
kissane(config)#username smarts password 0 cisco
kissane(config)#ip host smarts 192.168.1.1
6. Try to ping the loopback. You should not be able to see it. It should not have
shown up in the ip routing table either. The ISDN line comes up, stays active,
and then shuts off pretty quickly. Its actually faster than the routing protocol (I
used EIGRP). In order to make this work we need to set up some static routes and
a quad-zero (“gateway of last resort”) between the two.
smarts(config)#ip route 192.168.200.0 255.255.255.0 192.168.1.2
This route basically is saying. “in order to get to the 192.168.200.0/24 network
use the 192.168.1.2 interface.”
kissane(config)#ip route 192.168.100.0 255.255.255.0 192.168.1.1
kissane(config)#ip route 0.0.0.0 0.0.0.0 192.168.1.2
This route basically is saying, “in order to get to the 192.168.100.0/24 network
use the 192.168.1.1 interface.” You should be able to ping and see all networks.
Now you should see:
kissane#ping 192.168.1.1
Type escape sequence to abort.
Sending 5, 100-byte ICMP Echos to 192.168.1.1, timeout is 2 seconds:
