So I am doing a Lab for one of my classes involving ipv6 and routing using EIGRP. When I set-up the network and assign the router interfaces with IPV6 address I get an issue pinging the whole network. On the serial portion of the network, I can ping any port that has an IP assigned to it and using a serial connection and this is vice-versa with the other half of the network using ethernet for connectivity. I, unfortunately, can't ping an interface that is using ethernet or serial if ping from a router using opposite interface connection.

One big problem you seem to have with the serial interfaces is that you are not connecting DTE to DCE. You must set the clock rate on one side of the serial connection to set the interface as DCE, otherwise you are trying to connect DTE to DTE, and that does not work. You need to connect DTE to DCE.

For example, R2:

interface Serial2/0
 no ip address
 ipv6 address 2001:FACE:1111:F001::1/64
 serial restart-delay 0
!

connects to R5:

interface Serial2/0
 no ip address
 ipv6 address 2001:FACE:1111:F001::2/64
 serial restart-delay 0
!

but you do not set the clock rate on either side, and you must do that to set one side to DCE.

You could do something like R5:

interface Serial2/0
 clock rate 64000

You need to go through all your serial links and set one side to DCE by setting the clock rate.


routing using EIGRP.

I do not find any EIGRP configuration at all in any of your configurations. You will need to set up a routing protocol, such as EIGRP, or you will need to configure static routes in order for all the networks to reach all the other networks. A router must be told how to reach a network, and there are three ways a router learns how to reach other networks:

  1. A router inherently knows about directly connected networks.
  2. A router can be configured with static routes
  3. A router can dynamically learn routes through a routing protocol
