k. configure router r6 for ospf with a different process id than used thus far. do not configure r6’s e0 for ospf. l. configure router r8 to be in the same ospf area as router r6. put router r8’s interface e0&lo0 into the ospf routing process. configure router r6 so that its s1 interface speed is correctly reflected in the ospf metrics without using the “ip ospf cost xxx” command. m. configure ospf message-digest authentication between routers r6 & r8. n. change the ospf hello interval between routers r6 & r8 to 45 seconds. o. configure router r8 suing the “ip ospf cost” command such that the speed of the link for interface s0 is correctly reflected in the ospf metrics. p. change the ospf transmit interval delay to 10 seconds between routes r6 & r8. q. add a default route to router r2 that points to 137.20.20.2. configure one static route on router r2 so that full connectivity to r4’s interface e0 is available. you will notice that the default gateway of router r2 has a lower administrative cost than the one learned via router r1. as a result, the other default route never makes it in the routing table for router r2. r. you will notice that r2 can’t ping the serial interfaces between routers r3 & r4. fix this problem by only making changes to router r3 without static routes. 3. bgp configuration -15 pts (1 hour) a. configure router r4 in bgp autonomous system 1. b. create a static route to null0 router r4 and redistribute into bgp. c. create a loopback interface on r4 and add its network to bgp d. when adding the first loopback to bgp use a class a address with a 24-bit mask. the network that was added to bgp from the first loopback address should appear in the routing table of other routers as “ b 44.1.1.0…” e. create another loopback on router r4 with a class a address and put this network into rip and redistribute rip into bgp. f. configure router r3 in bgp autonomous system 1 and use interface loopback 0 as the update source. g. configure routers r1, r2, and r5 in bgp autonomous system 2, only use one neighbor x.x.x.x remote-as 2 command on routers r2, r3. &r5 for autonomous system 2. h. place routers r6 and r8 in bgp autonomous system 3. i. configure bgp authentication between router r6 & r8. j. configure a loopback interface on router r8 and enable rip for this network. redistribute this rip network into ospf. k. redistribute the ospf routing process that contains routers r6 and r8 into bgp. l. you are not allowed to add any static routes to router r8 during this exercise. m. configure router r6 such that all bgp routes learned from router r5 have a local preference of 300.
