Route maps in their simplest form consist of a line including the route map name, a permit or deny statement, and a number, followed by descriptions of one or more actions to carry out. Here's a simple route map: route-map TAG-EIGRP permit 10 set tag 3 The first line lists the name of the route map, the keyword permit, and the number 10 (this is the default; the numbers are used to order multiple entries in a route map, and as there's only one entry here, it doesn't really matter what the number is). The keyword permit says to perform the actions specified below the opening line. The next line shows the action to be taken for this route map entry, which is "Set the tag to a value of 3." Once you've created the TAG-EIGRP route map, you can call it using the route-map keyword and the route map's name in the EIGRP redistribute command: R2(config-router)#redistribute connected route-map TAG-EIGRP This command redistributes connected routes into EIGRP using the default metric and applies the tag set in the TAG-EIGRP route map. To see whether your tag has been implemented, look in the EIGRP topology table for the specific routes you believe should be tagged. To illustrate, I've applied this route map to R3 in the network shown in Figure 11-6. Here's what R2's EIGRP topology table looks like for the route 50.50.50.0/24: R2#sho ip eigrp top IP-EIGRP Topology Table for AS(100)/ID(10.10.10.2) Codes: P - Passive, A - Active, U - Update, Q - Query, R - Reply, r - reply Status, S - sia Status Chapter 11: Redistribution P 10.10.10.0/24, 1 successors, FD is 28160 via Redistributed (281600/0) P 20.20.20.0/24, 1 successors, FD is 28160 via Connected, FastEtherneto/1 P 50.50.50.0/24, 1 successors, FD is 156160, tag is 3 via 20.20.20.3 (156160/128256), FastEtherneto/1 And here is the detail for 50.50.50.0/24 on R3. The source is Rconnected, which means it was learned from the redistributed connected command: R3#sho ip eigrp top 50.50.50.0/24 IP-EIGRP (AS 100): Topology entry for 50.50.50.0/24 State is Passive, Query origin flag is
