IPv6 defines multiple types of unicast addresses, including the unspecified address, loopback address, global unicast address, link-local address, and unique local Packets sent toĪn IPv6 unicast address are delivered to the interface identified by that address. Since each interface belongs to a node, the IPv6 unicast address of any interface can identify the relevant node. IPv6 Unicast AddressĪn IPv6 unicast address identifies an interface. Instead, a multicast addressĬan be used as a broadcast address. Unlike IPv4, there is no broadcast IPv6 address. GigabitEthernet GigabitEthernet IEEE 802.IPv6 addresses can be classified as unicast, multicast, or a new class called anycast. Hint: for default route in Ipv4 we use 0.0.0.0 0.0.0.0 but for Ipv6 we will use ::/0 Step 4) Now I will do Default route on R10 and I will use next hop address Step 3) Hint: remember to enable IPV6 unicast-routing on R10 I go to R4 and create one Loopback address on R4# Success rate is 100 percent (5/5), round-trip min/avg/max = 0/1/8 msīut if I had some loopback address on the R4, then R10 can not ping that loopback address, we can use same concept as above or I Can show you the concept of Default route. Sending 5, 100-byte ICMP Echos to FEC0:1000::4, timeout is 2 seconds: Sending 5, 100-byte ICMP Echos to FEC0:1000::3, timeout is 2 seconds: Success rate is 100 percent (5/5), round-trip min/avg/max = 0/0/1 ms Sending 5, 100-byte ICMP Echos to FEC0:1000::2, timeout is 2 seconds: Success rate is 100 percent (5/5), round-trip min/avg/max = 0/0/0 ms Sending 5, 100-byte ICMP Echos to FEC0:1000::1, timeout is 2 seconds: Now If I try to ping from R4 to the loopback address of R10, it will work. Now I will just use up arrow key and put the rest of loopback network GigabitEthernet GigabitEthernet IEEE 802.3z Now we will configure it on R4 (using the ? mark) I should be able to ping all loopback address located on R10 We must do above commands for all Loopback address, since the goal is that seated at R4 Step 2) Now I will configure Static Route, in here I need to put the destination Network inside my R4 router Inspect Context-based Access Control Engine General-prefix Configure a general IPv6 prefix

Hint: on global Configuration start with IPV6?Įnter configuration commands, one per line. So remember you need enable unicast-routing ON1 – OSPF NSSA ext 1, ON2 – OSPF NSSA ext 2 O – OSPF intra, OI – OSPF inter, OE1 – OSPF ext 1, OE2 – OSPF ext 2 I1 – ISIS L1, I2 – ISIS L2, IA – ISIS interarea, IS – ISIS summary

Right now when i go to R4#show ipv6 route i do not see the loopback from R10 why?Ĭodes: C – Connected, L – Local, S – Static, R – RIP, B – BGP Here is R10 with so many loopback address: In here we have R4 and R10 with the following:

Ipv6 loopback
