LAB 18: IPv6 OSPF Summarization on ASBR

 

Task 1: Configure IPv6 OSPF Summarization​​ 

 

  • In the configuration mode of router configure 4 loopbacks with network​​ address in sequence​​ 

 

R1:

interface loopback 100 

ipv6 address 100:0:0::1/64

exit

interface loopback 101

ipv6 address 100:0:1::1/64

exit

interface loopback 102

ipv6 address 100:0:2::1/64

exit

interface loopback 103

ipv6 address 100:0:3::1/64

exit

 

Step 2​​  ​​​​ Redistribute external 100 network on ASBR.

 

R1:

ipv6 router ospf 1

redistribute connected subnets

exit

 

(Redistributed connected will redistribute its connected network. Subnet will allow classless routes in OSPF process.)

 

Step 3 ​​ Verify routes on neighbor router routing table

 R2#show ipv6 route

! (Shows router’s routing table and IPv6 entries)

 

IPv6 Routing Table - default - 26 entries

  • Configure IPv6 OSPF Not So Stubby Area

! (When loop50 is redistributed in stub area, external routes LSA 5 will no propagate​​ in stub area and hence cannot be seen in any other router’s routing table. To make seen this redistributed route to all other routers, replace stub area to Not So Stubby Area.)

ipv6 router ospf 1

Task 2: ​​ Verification:

  • Verify routes on neighbor router routing table
