Figure 6-2 Specifying FEC Attributes

The FEC Details Table helps define the FEC through a set of match rules, which are combinations of TCP, UDP, and IP header fields. FECs are determined by taking a logical AND of the column settings in a row and by taking a logical OR of each of the rows. In other words, for a packet to qualify for a particular FEC, the IP header fields must satisfy every condition of at least one row of the defined FEC. For example, a FEC that consists only of email and ftp traffic would be specified as shown in Figure 6-3.

Therefore, if the IP header of a packet contained either email or FTP, it would qualify for the FEC defined in Figure 6-3, and would be sent over the corresponding LSP.
