Lab – Troubleshooting Basic Frame Relay

i - IS-IS, su - IS-IS summary, L1 - IS-IS level-1, L2 - IS-IS level-2

ia - IS-IS inter area, * - candidate default, U - per-user static route

o - ODR, P - periodic downloaded static route, H - NHRP, l - LISP

+ - replicated route, % - next hop override

Gateway of last resort is not set

D 192.168.1.0/24 [90/2172416] via 10.1.1.1, 00:27:32, Serial0/0/1

b. Issue a show frame-relay map command on both R1 and R3. Are the DLCIs active? ________ Yes

R1# show frame-relay map

Serial0/0/0 (up): ip 10.1.1.1 dlci 101(0x65,0x1850), static,

CISCO, status defined, active

Serial0/0/0 (up): ip 10.1.1.2 dlci 101(0x65,0x1850), static,

broadcast,

CISCO, status defined, active

R3# show frame-relay map

Serial0/0/1 (up): ip 10.1.1.1 dlci 201(0xC9,0x3090), static,

broadcast,

CISCO, status defined, active

Serial0/0/1 (up): ip 10.1.1.2 dlci 201(0xC9,0x3090), static,

CISCO, status defined, active

Reflection

Describe the troubleshooting methodology you used to solve the issues in this lab. Outline the steps that were

necessary to successfully meet the assignment.

Answers will vary. Hopefully, students will answer that breaking a problem down into smaller steps helps with

troubleshooting. Solving IP addressing, then EIGRP and then Frame Relay issues separately instead of all at

once can make troubleshooting easier.
