Scenario
In this activity, you must implement EIGRP for IPv4 and IPv6 on two separate networks. Your task includes enabling EIGRP, assigning router IDs, changing the hello timers, and limiting EIGRP advertisements.
Requirements
EIGRP for IPv4
- Implement EIGRP on IPv4-enabled routers using Autonomous System 1.
- Use a single classful network address to advertise the loopback interfaces.
- Use the wildcard mask to advertise the /30 networks between R1, R2 and IPv4-Edge.
- Use the default passive interface method and only allow EIGRP updates out the active EIGRP serial interfaces.
R1(config)# router eigrp 1 R1(config-router)# passive-interface default R1(config-router)# no passive-interface Serial0/0/0 R1(config-router)# network 172.31.0.0
R2(config)# router eigrp 1 R2(config-router)# passive-interface default R2(config-router)# no passive-interface Serial0/0/1 R2(config-router)# network 10.0.0.0
IPv4-Edge(config)# router eigrp 1 IPv4-Edge(config-router)# passive-interface default IPv4-Edge(config-router)# no passive-interface Serial0/0/0 IPv4-Edge(config-router)# no passive-interface Serial0/0/1 IPv4-Edge(config-router)# network 172.31.6.0 0.0.0.3 IPv4-Edge(config-router)# network 10.10.8.0 0.0.0.3
- Configure a directly attached default route on IPv4-Edge and propagate it in EIGRP updates.
IPv4-Edge(config)# ip route 0.0.0.0 0.0.0.0 Serial0/1/0 IPv4-Edge(config)# router eigrp 1 IPv4-Edge(config-router)# redistribute static
- Configure the serial interfaces between R1, R2 and IPv4-Edge to send hellos every 10 seconds.
R1(config)# interface s0/0/0 R1(config-if)# ip hello-interval eigrp 1 10
R2(config)# interface s0/0/1 R2(config-if)# ip hello-interval eigrp 1 10
IPv4-Edge(config)# interface s0/0/0 IPv4-Edge(config-if)# ip hello-interval eigrp 1 10 IPv4-Edge(config-if)# interface s0/0/1 IPv4-Edge(config-if)# ip hello-interval eigrp 1 10
- R1 and R2 should have a default route in the routing table (D*EX).
- Verify R1 and R2 can ping the IPv4 Server. IPv4 Server should also be able to ping every loopback address on R1 and R2.
EIGRP for IPv6
- Implement EIGRP for IPv6 on the IPv6-enabled routers using Autonomous System 1.
- Assign IPv6-Edge with the router ID of 1.1.1.1
- Assign R3 with the router ID of 3.3.3.3
- Assign R4 with the router ID of 4.4.4.4
IPv6-Edge(config)# ipv6 unicast-routing IPv6-Edge(config)# ipv6 router eigrp 1 IPv6-Edge(config-rtr)# eigrp router-id 1.1.1.1 IPv6-Edge(config-rtr)# no shutdown IPv6-Edge(config-rtr)# interface Serial0/0/0 IPv6-Edge(config-if)# ipv6 eigrp 1 IPv6-Edge(config-if)# interface Serial0/0/1 IPv6-Edge(config-if)# ipv6 eigrp 1
R3(config)# ipv6 unicast-routing R3(config)# ipv6 router eigrp 1 R3(config-rtr)# eigrp router-id 3.3.3.3 R3(config-rtr)# no shutdown R3(config-rtr)# interface Loopback0 R3(config-if)# ipv6 eigrp 1 R3(config-if)# interface Loopback1 R3(config-if)# ipv6 eigrp 1 R3(config-if)# interface Loopback2 R3(config-if)# ipv6 eigrp 1 R3(config-if)# interface Loopback3 R3(config-if)# ipv6 eigrp 1 R3(config-if)# interface Serial0/0/0 R3(config-if)# ipv6 eigrp 1
R4(config)# ipv6 unicast-routing R4(config)# ipv6 router eigrp 1 R4(config-rtr)# eigrp router-id 4.4.4.4 R4(config-rtr)# no shutdown R4(config-rtr)# interface Loopback8 R4(config-if)# ipv6 eigrp 1 R4(config-if)# interface Loopback9 R4(config-if)# ipv6 eigrp 1 R4(config-if)# interface Loopback10 R4(config-if)# ipv6 eigrp 1 R4(config-if)# interface Loopback11 R4(config-if)# ipv6 eigrp 1 R4(config-if)# interface Serial0/0/1 R4(config-if)# ipv6 eigrp 1
- Configure a directly attached default route on IPv6-Edge and propagate it in EIGRP updates.
IPv6-Edge(config)# ipv6 route ::/0 Serial0/1/0 IPv6-Edge(config)# ipv6 router eigrp 1 IPv6-Edge(config-rtr)# redistribute static
- R3 and R4 should show a default external route in the routing table.
- Verify R3 and R4 can ping the IPv6 Server. IPv6 Server should also be able to ping every loopback address on R3 and R4.
Suggested Scoring Rubric
Note: Packet Tracer does not currently grade EIGRP for IPv6 summary routes. Therefore, part of your grade depends on routing table verification by your Answer.
| Scored Work | Possible Points | Earned Points |
| IPv6-Edge Routing Table | 10 | |
| Packet Tracer Score | 90 | |
| Total Score | 100 |
