EIGRP IPV6Now I will do small Lab: R4=10.10.10.4R10=10.10.10.10 connected via LAN link Also I will have IPV6 as follow: r4 f0/0=2001:4444::4/64r10 f0/0=2001:4444::10/64

EIGRP IPV6

In here we have R4 and R10 with the following : Here is R4#Show run: nterface FastEthernet0/0 ip address 10.10.10.4 255.255.255.0 duplex auto speed auto ipv6 address 2001:4444::4/64

EIGRP IPV6 Here is R10 with so many loopback address

interface Loopback0 ip address 100.100.100.100 255.255.255.0!interface Loopback1 no ip address ipv6 address FEC0:1000::1/128!interface Loopback2 no ip address ipv6 address FEC0:1000::2/128!

EIGRP IPV6

interface Loopback3 no ip address ipv6 address FEC0:1000::3/128!interface Loopback4 no ip address ipv6 address FEC0:1000::4/128!interface FastEthernet0/0 ip address 10.10.10.10 255.255.255.0 duplex auto speed auto ipv6 address 2001:4444::10/64

EIGRP IPV6

Right now when i go to R4#show ipv6 route i do not see the loopback from R10 why?Since i need to run EIGRP ipv6

R4#show ipv6 route IPv6 Routing Table - 3 entriesCodes: C - Connected, L - Local, S - Static, R - RIP, B - BGP U - Per-user Static route, M - MIPv6 I1 - ISIS L1, I2 - ISIS L2, IA - ISIS interarea, IS - ISIS summary O - OSPF intra, OI - OSPF inter, OE1 - OSPF ext 1, OE2 - OSPF ext 2 ON1 - OSPF NSSA ext 1, ON2 - OSPF NSSA ext 2 D - EIGRP, EX - EIGRP external

EIGRP IPV6

As we see i need to do unicast-routingNow I go under the int f0/0 and do IPV6?

EIGRP IPV6

Hint: As we see under the ipv6 router EIGRP 100, I need to give no shutR4(config)#ipv6 router eigrp ? <1-65535> Autonomous system numberR4(config)#ipv6 router eigrp 100R4(config-rtr)#no shutR4(config-rtr)#

EIGRP IPV6

Now I will do same concept on R10 --- But make sure advertise it under all loopback.

As we see I do not see nothing? why not?Let’s look my neighbors R4#show ipv6 eigrp neighbors IPv6-EIGRP neighbors for process 100 Now neighbors why? Since when I look at R10#show run; I see I forgot to advertise under int f0/0 R10#show run interface FastEthernet0/0ip address 10.10.10.10 255.255.255.0duplex autospeed autoipv6 address 2001:4444::10/64

EIGRP IPV6

As we see as soon as I did advertise under F0/0 of R10 I see some activity since I am sending hello packets to R4 and r4 has already send hello packets to me Let’s check the neighbors:R4#show ipv6 eigrp neighbors IPv6-EIGRP neighbors for process 100H Address Interface Hold Uptime SRTT RTO Q Seq (sec) (ms) Cnt Num0 Link-local address: Fa0/0 13 00:02:17 40 1000 0 1 FE80::201:96FF:FE3D:E001

EIGRP IPV6

So summary 1) Make sure you enable ipv6-unicast routing2) Make sure you do Global configuration with ipv6 ? (Give no shut)3) Make sure advertise it under the interface With int f0/0 ipv6?
