Migrating X.25 over PSI to X.25 over TCP/IP (XOT)

Example 20 Configuration on Host B: X.25 interface: /etc/x25/x121_to_ip_map
XOT Specific Configuration File:
#
# X.25 to IP Map File for SVCs, as per RFC 1613
#
#Destination X.21 Destination
# Address IP Address
# None
# PVC Routing Information, as per RFC 1613
# Local(LCN), Remote(LCN), LocalInterfacename,
RemoteInterfacename,Remoteip
pvcroute 1 1 xot0 Serial0/0/0 10.0.0.1 #PVC channel 1 mapped to channel 1
pvcroute 2 2 xot0 Serial0/0/0 10.0.0.1 #PVC channel 2 mapped to channel 2
pvcroute 3 3 xot0 Serial0/0/0 10.0.0.1 #PVC channel 3 mapped to channel 3
pvcroute 4 4 xot0 Serial0/0/0 10.0.0.1 #PVC channel 4 mapped to channel 4
Configuration on the X.25/LAPB to XOT Router:
This was verified with Cisco 2851 router, and the following X.25 routing table entries would have
to be added.
Cisco2851#configure terminal
Cisco2851(config)# interface Serial 0/0/0
Cisco2851(config)# x25 pvc 1 xot 10.0.0.2 interface serial 0/0/0 pvc 1
Cisco2851(config)# x25 pvc 2 xot 10.0.0.2 interface serial 0/0/0 pvc 2
Cisco2851(config)# x25 pvc 3 xot 10.0.0.2 interface serial 0/0/0 pvc 3
Cisco2851(config)# x25 pvc 4 xot 10.0.0.2 interface serial 0/0/0 pvc 4
Cisco2851(config)#end
Rest of the L3 and L2 parameters for X.25 should be consistent between the participating hosts
and the router.
