There appears to be problems on Router R1 and R2 in the network provided. Correct the problems as soon as possible and restore IPv6 network connectivity.
There are errors in the Internet Protocol version 6 (IPv6) setup on both routers. The PCs and switches
do not require configuration. Make corrections to the network setup as needed to fix the problems.
Note: Use the password ciscopress for all routers in this lab.
The internetwork is having some problems, and it is your job to solve the problems. The trouble
ticket for this is shown as follows. Investigate the network problems, make corrections to network
as necessary, and report your findings.
You can find the problems in this lab by examining the network configuration and looking for
errors. The topology for this network is provided in Figure 1. Note: The switches in this network
pass data but do not require configuration.
The IP addresses for all the applicable interfaces used in this exercise are listed in Table 1.
Solutions
```
Router 1
Problem: Incorrect subnet mask on S0/0/0.
Solution:
conf t
int s0/0/0
ipv6 address 2002:A10B:0:1::1/64
end
Router 2
Problem: IPv6 unicast routing is disabled.
Solution:
conf t
ipv6 unicast-routing
end
