3. bgp configuration –15pts (1h)
a. place router r4 in bgp as 1 and router r3 in bgp as 2. create two static routes to null0 using a class a address with a 24-bit mask on r4 and inject into bgp such that router r3 can see it. use loopbacks as the update source on both routers r3 and r4. create loopback interface as necessary.
b. filter one of the static routes with a route-map statement on router r4.
c. configure bgp on router r4 such that the sub-netted class a route is seen. for example, the bgp route on router r3 could be 41.1.1.0 not 41.0.0.0.
d. configure a second loopback interface on router r4 at 200.200.200.1/24 and enable rip on this router for this network. inject this route and the previous one with a metric of 5.
e. configure router r2, r1, and r5 in bgp as3. use only one neighbor x.x.x.x remote-as x statement on routers r2 and r5.
f. create a static route on router r2 (ip route 22.1.1.0 255.255.255.0 null0) inject this route into bgp. make sure the other routers running bgp can see this route.
g. also make sure all routers can ping 200.200.200.1.
you have completed lab 4 compare your configurations to the ones we provided. often there is more than one to complete a task so your configuration may be different than ours. if your configuration are different than ours make sure you understand how to complete the lab with our configurations too
lab5
at the end of this lab verify connectivity to all ports. you should be able to ping every interface from any router. (don’t worry about being able to ping a local frame-relay interface. please disregard this statement if you are asked to filter packets. routes or other specific tasks.)
1. initial configuration & ospf -35pts (2 h)
a. use the pre-configuration files to apply proper ip addresses to the router interfaces. add ip addresses as needed as shown on the network diagram. you may have to add additional ip addresses to complete some tasks.
b. configure router r2’s ethernet interfaces with ip address 137.20.20.1/24 and router r2’s default route to 137.20.20.2.
c. use a 24-bit mask unless told to use otherwise.
d. create a loopback interface on router r2 with 200.200.200.1/24.
e. connect router r3, r4, r5, and r6 over frame-relay. configure router r5 using sub-interfaces.
f. connect routers r3, r4, r5 and r6 over frame-relay. configure router r5 and router r4 on a different subnet.
g. configure ospf on router r3’s interface s1, router r6’s interface s1, and router r5’s sub-interface s1.1 for ospf area 10, place r5’s and r2’s ethernet interface in ospf area 0.
h. configure the connection between router r5’s interface s1.2 and router r4 for igrp.
i. configure router r6’s ethernet e0 as ospf area 6. configure router r3’s token-ring interface to0 as ospf area 3. configure two loopback interfaces on router r3 with networks that contain at most 30 hosts and put both loopbacks in the same area as the token-ring interface. summarize the loopback subnets and router r3’s interface to0 to appear as one route to ospf.
