| 1 | Table 10-8 shows the interfaces, interface addresses, and subnet masks of 11 routers. The table also designates that routers belong in the same area. Write Integrated IS-IS configurations for the routers, using the following guidelines: Make up your own System IDs for the routers. Use the shortest NETs possible. Configure routers as L1, L2, or L1/L2 as appropriate.
Table 10-8. Router information for Configuration Exercises 1 through 5.Router | Area | Interface | Address/Mask |
|---|
A | 0 | E0 E1 | 192.168.1.17/28 192.168.1.50/28 | B | 0 | E0 E1 | 192.168.1.33/28 192.168.1.51/28 | C | 0 | E0 S0 | 192.168.1.49/28 192.168.1.133/30 | D | 2 | S0 S1 | 192.168.1.134/30 192.168.1.137/30 | E | 2 | S0 S1 S2 | 192.168.1.142/30 192.168.1.145/30 192.168.1.138/30 | F | 2 | S0 S1 | 192.168.1.141/30 192.168.1.158/30 | G | 1 | E0 S0 | 192.168.1.111/27 192.168.1.157/30 | H | 1 | E0 E1 | 192.168.1.73/27 192.168.1.97/27 | I | 3 | E0 E1 S0 S1 | 192.168.1.225/29 192.168.1.221/29 192.168.1.249/30 192.168.1.146/30 | J | 3 | E0 E1 | 192.168.1.201/29 192.168.1.217/29 | K | 3 | EO S0 | 192.168.1.209/29 192.168.1.250/30 |
Tip: Draw a picture of the routers and subnets first. |
| 2 | Configure IPv6 on each router, in multi-topology mode. Use the address 2001:db8:0:x::/64, where x is the hexadecimal value of the subnet (4th octet only) of the corresponding IPv4 address on each link. |
| 3 | Configure authentication between all routers in area 2 of Table 10-8. Use the password "Eiffel" between routers D and E; use the password "Tower" between routers E and F. Use type md5 authentication. |
| 4 | Configure level 1 authentication in area 1 of Table 10-8. Use the password "Scotland." Use cleartext passwords with no key chains. |
| 5 | Configure level 2 authentication on the routers in Table 10-8. Use the password "Vienna." Use cleartext passwords with key chains. |
| 6 | Configure the L1/L2 routers in areas 0, 1, and 3 in Table 10-8 to summarize their L1 addresses, both IPv4 and IPv6. |
