Topology
Notice!
IPv6 addresses have changed. Follow the below topology diagram and tasks to accomplish the goals.
Pic1. IPv6 Topology Diagram.
Task 1
Modify previous lab's configuration of OSPFv3 between R3, R4, and R6 as shown in Pic. 2:
Pic. 2
Task 2
Enable OSPFv3 between R4 and R6. Broadcast network should use addresses according to the topology diagram with ::x as their host portion, where 'x' is the router number.
Task 3
Ensure that R3 uses R6 as its primary gateway towards FC00:1:1:2D::/64. In case of R6 being unavailable, R3 is to choose R4 to reach the network in question. Configuration should be done on R3.
Solution
Task 1
Modify previous lab's configuration of OSPFv3 between R3, R4, and R6 as shown in Pic. 2.
R3 Config:
!interface Serial0/1
encapsulation frame-relay
ipv6 address FE80::3 link-local
ipv6 address FC00::3/64
ipv6 ospf network point-to-multipoint
ipv6 ospf 1 area 0
clock rate 2000000
frame-relay map ipv6 FC00::4 314 broadcast
frame-relay map ipv6 FC00::6 316 broadcast
frame-relay map ipv6 FE80::6 316
frame-relay map ipv6 FE80::4 314
no frame-relay inverse-arp
!
R4 Config:
!
interface Serial0/0
encapsulation frame-relay
ipv6 address FE80::4 link-local
ipv6 address FC00::4/64
ipv6 ospf network point-to-multipoint
ipv6 ospf 1 area 0
clock rate 2000000
frame-relay map ipv6 FE80::3 413 broadcast
frame-relay map ipv6 FC00::3 413
no frame-relay inverse-arp
!
R6 Config:
!
interface Serial0/0
encapsulation frame-relay
ipv6 address FE80::6 link-local
ipv6 address FC00::6/64
ipv6 ospf network point-to-multipoint
ipv6 ospf 1 area 0
clock rate 2000000
frame-relay map ipv6 FE80::3 613 broadcast
frame-relay map ipv6 FC00::3 613
no frame-relay inverse-arp
!
Task 2
Enable OSPFv3 between R4 and R6. Broadcast network should use addresses according to the topology diagram with ::x as their host portion, where 'x' is the router number.
R4 Config:
!interface FastEthernet0/0
speed 100
full-duplex
ipv6 address FC00:1:1:2D::4/64
ipv6 ospf 1 area 0
!
R6 Config:
!interface FastEthernet0/1
ip address 172.16.46.6 255.255.255.0
speed 100
full-duplex
ipv6 address FC00:1:1:2D::6/64
ipv6 ospf 1 area 0
!
Verfication:
Pic. 3 - R4 and R6 OSPFv6 Neighbors.
Task 3
Ensure that R3 uses R6 as its primary gateway towards FC00:1:1:2D::/64. In case of R6 being unavailable, R3 is to choose R4 to reach the network in question. Configuration should be done on R3.
Before path influencing:
Pic. 4.
R3 Config:
!interface Serial0/1
ipv6 ospf neighbor FE80::4 cost 65
!
Routing table after the configuration change:
