1: | What is dynamic mapping? |
A1: | Using Inverse ARP to request the next hop protocol address for a specific DLCI . |
2: | For Router-frame, map the IP address 10.0.0.1 to DLCI = 100, using the IETF encapsulation. |
A2: | Router-frame(config-if)# frame-relay map ip 10.0.1.1 100 broadcast ietf |
3: | Can you use IP unnumbered with Frame Relay? |
A3: | You can, but you must use point-to-point subinterfaces and static routes or dynamic routing for your traffic to get routed. |
4: | Can you ping your own interface address? Can you ping one spoke router from another? |
A4: | In point-to-point interfaces, you can. In point-to-multipoint interfaces, you cannot, unless you configure Frame Relay map. |
5: | What happens to deleted subinterfaces? |
A5: | Deleted subinterfaces show up as deleted until the router is reloaded. |
6: | In point-to-point configurations that are running EIGRP, type the command for Router-frame that prevents all routing updates for interface Serial3/0:0.64? |
A6: | Router-frame(config)# passive-interface Serial3/0:0.64 |
7: | Configure the Frame Relay broadcast queue for Router-framesubinterface S3/0:0.71 with queue size 100, byte rate 1200, and packet rate 120. |
A7: | Router-frame(config-if)# frame-relay broadcast-queue 100 1200 120 |
8: | Can you configure the Cisco router as a DCE? |
A8: | You can, if you use the frame-relay intf-type [dce nni] command in the general configuration mode. |
9: | Under the interface Serial3/0:0.200, what is the backup delay command with enable delay = 5 seconds and disable delay = 10 seconds? |
A9: | Router-frame(config-if)# backup delay 5 10 |
10: | For Router-frame and interface Serial1, what is the command for TCP header compression, which is active only for the destinations that are sending compressed headers? |
A10: | Router-frame(config-if)# frame-relay ip tcp header-compression passive |
11: | For Router-frame and interface Serial4/2:0.200, define that FRF9 payload compression will be performed on CSA 3. |
A11: | Router-frame(config-if)# frame-relay payload-compression FRF9 stac csa 3 |
12: | Enable the multicast routing in Router-frame. |
A12: | Router-frame(config)# ip multicast-routing |
13: | In Router-frame, for interface Serial4/2:0.100, define the upper limit of the rate for traffic shaping to 128000. |
A13: | Router-frame(config-if)# traffic-shape rate 128000 |
14: | What Frame Relay timer defines the Cisco autosense feature? How do you configure it? |
A14: | N391. At every N391 interval, LMI autosenses the LMI type. The default is 6 attempts in 60 seconds. It is configurable with the command frame-relay lmi-n391dte value. |
