Hi Bill,

Telnet to LAT Practice Lab
--------------------------
An easy lab to start your weekend
[R1]--[R2]--[R3]
Router 1 is running strictly TCP/IP.
Router 3 is running strictly LAT and is advertising a LAT service called
COOL5.
R1
int S1
ip address 157.89.8.1 255.255.255.0
R3
lat service COOL5 autocommand sh protocols
int S0
lat enable
Configure Router 2 so that R1 can connect to R3's LAT service. You may not
make any changes to R1 or R3. For router R1 connecting to this LAT service
should be a one-step process.
For Answer:
Protocol translation allows a router to translate from one protocol,
like TCP to another protocol like LAT.
Two-step protocol translation works like this
User telnets into the router and logs into the router.
User then LATs to the lat device.
might look like this:
telnet 157.89.8.2
Welcome to R2
username: john
password: secret
R2#
R2#LAT COOL5
Welcome to COOL5
.....
One-Step Protocol translation work like this
User telnets to an ip address monitored by the router, the router
automatically connects them to the lat service.
might look liks this:
telnet 157.89.8.3
Welcome to COOL5
.....
The answer:
R2
translate tcp 157.89.8.3 lat COOL5
int s0
ip address 157.89.8.2 255.255.255.0
int s1
lat enable
----------------------------------------------------------------------------

Your challenge. Configure a LAT service on R3 called COOLBEANS that
automatically displays the version information when a user
connects to it.
R1 should be able to access this service.
Current Minimalized Config:
R1
int serial 0
ip address 10.10.12.1 255.255.255.0
R2
int serial 0
ip address 10.10.12.2 255.255.255.0
int serial 0
ip address 10.10.23.2 255.255.255.0
R3
int serial 0
ip address 10.10.23.3 255.255.255.0
Stumped??? The answer is here.
at only needs to be enable on routers R1 and R3. Lat is a non routable
protocol so it only need to bridged through R2.
R1
int s0
lat enable
R2
int s0
bridge-group 1
int s1
bridge-group 1
R3
lat service enable
lat service COOLBEANS autocommand show version
int s1
lat enable
