NETGEAR 8800 User Manual Table 37. Policy Match Conditions (Continued) Match Condition Description tag ; Where is a 4-byte unsigned number. route-origin [direct | static | icmp | egp | ggp | hello | rip | isis | esis | cisco-igrp | ospf | bgp | idrp | dvmrp | mospf | pim-dm | pim-sm | ospf-intra | ospf-inter | ospf-extern1 | ospf-extern2 | bootp | e-bgp | i-bgp | mbgp | i-mbgp | e-mbgp] Matches the origin (different from BGP route origin) of a route. A match statement "route-origin bgp" will match routes whose origin are "I-bgp" or "e-bgp" or "I-mbgp" or "e-mbgp". Similarly, the match statement "route-origin ospf" will match routes whose origin is "ospf-inta" or "ospf-inter" or "ospf-as-external" or "ospf-extern-1" or "ospf-extern-2" Note: When entering an AS number in a policy file, you must enter a unique 2-byte or 4-byte AS number. The transition AS number, AS 23456, is not supported in policy files. Autonomous system expressions The AS-path keyword uses a regular expression string to match against the autonomous system (AS) path. Table 38 lists the regular expressions that can be used in the match conditions for Border Gateway Path (BGP) AS path and community. Table 39 shows examples of regular expressions and the AS paths they match. Table 38. AS Regular Expression Notation Character N N1 - N2 [Nx ... Ny] [^Nx ... Ny Definition As number Range of AS numbers, where N1 and N2 are AS numbers and N1 < N2 Group of AS numbers, where Nx and Ny are AS numbers or a range of AS numbers Any AS numbers other than the ones in the group Matches any number Matches the beginning of the AS path Matches the end of the AS path Matches the beginning or end, or a space Separates the beginning and end of a range of numbers Matches 0 or more instances Matches 1 or more instances Matches 0 or 1 instance Chapter 14.
