if you are looking for config example, it should be like this:

X25 routing

!

interface Serial0

no ip address

encapsulation x25 dce

clock rate 64000

!

interface Serial1

no ip address

encapsulation x25 dce

clock rate 64000

!

x25 route 4321 interface Serial0

x25 route 1234 interface Serial1

!

you said the routers will act as x25 switchers. so what ip you want to ping?

if you can add IP to the diagram and x25 addresses.

other question: why are you using 2 x25 switchers in serial. only one switcher could be enough

i think if your servers has x25 addresses and not IP addresses, and they need to communicate using x25 packets only, so you do not need any IP address.

x25 switching just switch x25 packets at layer 2 like does public x25 service provider.

IP over x25 is an other thing. this works if your hosts use IP addressing and your wan network is x25.

so you sould have configs like i said:

rtr1:

X25 routing

!

interface Serial0

no ip address

encapsulation x25 dce

clock rate 64000

!

interface Serial1

no ip address

encapsulation x25

clock rate 64000

!

x25 route 4321 interface Serial0

x25 route 1234 interface Serial1


rtr2:

X25 routing

!

interface Serial0

no ip address

encapsulation x25 dce

clock rate 64000

!

interface Serial1

no ip address

encapsulation x25 dce

clock rate 64000

!

x25 route 4321 interface Serial1

x25 route 1234 interface Serial0

then use debug x25 packets to troubleshoot the connexions

Hi Pulkit,


Try with this config.


First router.

interface serial 0

ip address 131.108.1.3 255.255.255.0

x25 map ip 131.108.1.4 0

x25 pvc 4 ip 131.108.1.4



Second Router.

interface serial 0

ip address 131.108.1.4 255.255.255.0

x25 map ip 131.108.1.3 0

x25 pvc 4 ip 131.108.1.3



Hope this helps,



Regards,


Pravin

Hi,


The below config worked fine for me in the lab network.


Router 1

interface serial0/0

(config-if)#encapsulation x25 dce

(config-if)#x25 address 311082194567

(config-if)#ip address 10.60.8.1 255.255.248.0

(config-if)#x25 map ip 10.60.8.2 311082191234 broadcast


Rouetr2

(config)#interface serial0/0

(config-if)#encapsulation x25 dte

(config-if)#x25 address 311082191234

(config-if)#ip address 10.60.8.2 255.255.248.0

(config-if)#x25 map ip 10.60.8.1 311082194567 broadcast
