Now I will do small Lab: The Goal is that seated at R4 be able to ping all the loopback of R10 , in order to do this , we will cover Static Route.



R10= connected via LAN link


Also I will have IPV6 as follow:

r4 f0/0=2001:4444::4/64

r10 f0/0=2001:4444::10/64

In here we have R4 and R10  with the following:

Here is:

R4#Show run

interface FastEthernet0/0

ip address

duplex auto

speed auto

ipv6 address 2001:4444::4/64


Here is R10  with so many loopback address:

interface Loopback0

ip address


interface Loopback1

no ip address

ipv6 address FEC0:1000::1/128


interface Loopback2

no ip address

ipv6 address FEC0:1000::2/128


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

duplex auto

speed auto

ipv6 address 2001:4444::10/64


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

Since i need to run do ipv6 Static Route

R4#show ipv6 route

IPv6 Routing Table – 3 entries

Codes: 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

C   2001:4444::/64 [0/0]

via ::, FastEthernet0/0

L   2001:4444::4/128 [0/0]

via ::, FastEthernet0/0

L   FF00::/8 [0/0]

via ::, Null0



So remember you need enable unicast-routing


Hint: on global Configuration start with IPV6?

Here is my configuration on R4#


Step 1) Enable Unicast-routing on R4
