Configuration files
• Configuration file of Router A (the static address mapping)
#
sysname RouterA
#
interface Serial1/0/0
link-protocol fr
fr interface-type dce
fr map ip 202.38.163.252 100
fr dlci 100
ip address 202.38.163.251 255.255.255.0
#
return
The dynamic address mapping is similar to this, but there is no fr map ip 202.38.163.252 100.
• Configuration file of Router B (the static address mapping)
#
sysname RouterB
#
interface Serial1/0/0
link-protocol fr
fr map ip 202.38.163.251 100
ip address 202.38.163.252 255.255.255.0
#
return
The dynamic address mapping is similar to this, but there is no fr map ip 202.38.163.251 100.
8.14.3 Example for configuring frame relay switching routes
Networking requirements
You can implement the FR switching route function in a network with two or more routers. As
shown in Figure 8-7, Router B and Router C can be considered as routers for FR switching,
enabling the serial 1/0/0 on Router A and Serial 2/0/0 on Router D to interconnect with each
other through the FR switching of Router B and Router C.
