Ping make and break. (Question #54)
Consider two routers connected to each other via their serial interfaces over frame relay with the following configs
Router R1
RouterR2
The two routers are able to ping each other. However on R1 (or R2) if you try to ping its own serial interface the ping fails.
1. Do whatever is necessary to be able get each router's attempts to ping its own serial interface succeed.
2. After having done (1) cause the pings on R1 to its own serial interface to now fail again but do so with making any changes to the configuration of R1 itself.
Router R1
interface Serial2
ip address 10.0.0.1 255.255.255.0
encapsulation frame-relay
no fair-queue
frame-relay map ip 10.0.0.2 122
frame-relay interface-dlci 122
no frame-relay inverse-arp
RouterR2
interface Serial2
ip address 10.0.0.2 255.255.255.0
encapsulation frame-relay
no fair-queue
frame-relay map ip 10.0.0.1 221
frame-relay interface-dlci 221
no frame-relay inverse-arp
