ip alias command is typically used when you what to make a shortcut for a
command. A lot of people will create an alias for 'show ip route' for
example so all they have to type is 's' Here is an example on my router
where I created an alias for the exec command show ip route. This way I
only have to type 's' to see show ip route.
sf-1700-vpn(config)#alias exec s show ip route
sf-1700-vpn(config)#^Z
sf-1700-vpn#s
Codes: C - connected, S - static, I - IGRP, R - RIP, M - mobile, B - BGP
D - EIGRP, EX - EIGRP external, O - OSPF, IA - OSPF inter area
N1 - OSPF NSSA external type 1, N2 - OSPF NSSA external type 2
E1 - OSPF external type 1, E2 - OSPF external type 2, E - EGP
i - IS-IS, L1 - IS-IS level-1, L2 - IS-IS level-2, ia - IS-IS inter
area
* - candidate default, U - per-user static route, o - ODR
P - periodic downloaded static route
Gateway of last resort is 64.1.1.145 to network 0.0.0.0
64.0.0.0/29 is subnetted, 1 subnets
C 64.1.1.144 is directly connected, FastEthernet0/0
172.16.0.0/24 is subnetted, 1 subnets
C 172.16.0.0 is directly connected, Loopback0
10.0.0.0/24 is subnetted, 1 subnets
C 10.1.1.0 is directly connected, FastEthernet0/1
S* 0.0.0.0/0 [1/0] via 64.1.1.145
If you want to setup your terminal server so you only have to type R1 to
access your terminal server on line 2035 you would do the following. The IP
address should be the IP of your loopback on your terminal server.
Typically people use the loopback but you can use any active interface on
the router. But if you use an interface such as an Ethernet and that
interface goes down your reverse telnet won't work. So, its best to stick
with using a loopback.
ip host R1 2034 1.1.1.1
The part that is confusing is when you enter an ip host command you put the
terminal server's line number before the IP address. If you were to want to
telnet manually you would type 'telnet 1.1.1.1 2034'.
Hope this clears it up.
