Port Application Mapping (PAM) on a Cisco Router

The Cisco IOS router has a built-in feature called Port Application Mapping (PAM). This feature is commonly used in Context-Based Access Control (CBAC) or Zone-Based Policy Firewall (ZBF). You can use the show ip port-map command on a Cisco router to do a quick lookup of its built-in well-known TCP or UDP port numbers instead of going to the IANA website. You can use pipe (|) to narrow down a specific port. This is useful when creating access control list (ACL) on a router.

Configuring EIGRP for IPv6

EIGRP for IPv6 follows the same basic configuration style as for RIPng. The specific EIGRP for IPv6 configuration steps are as follows:

Step 1. Enable IPv6 routing with the ipv6 unicast-routing global command.

Step 2. Enable EIGRP using the ipv6 router eigrp <1 – 65535> global configuration command.

Step 3. Enable IPv6 on the interface, typically with one of these two methods:
* Configure an IPv6 unicast address on each interface, using the ipv6 address address/prefix-length [ eui-64 ] interface command.

* Configure the ipv6 enable command, which enables IPv6 and causes the router to derive its link-local address.

Step 4. Enable EIGRP on the interface with the ipv6 eigrp <ASN> interface subcommand (where the ASN matches the ipv6 router eigrp <ASN> global configuration command).

Step 5. Enable EIGRP for IPv6 with a no shutdown command while in EIGRP configuration mode, if EIGRP is currently disabled.

Step 6. If no EIGRP router ID has been automatically chosen, because of not having at least one working interface with an IPv4 address, configure an EIGRP router ID with the router-id rid command in EIGRP configuration mode.
