Table 7-9 shows examples of AS path pattern matching using the ip /jointfilesconvert/99069/bgp_routes

command with a <simplified_regular_expression>.

^ Following pattern occurs at the beginning of the AS path

$ Preceding pattern occurs at the end of the AS path

| Logical OR operation: Match this or that

_Exact match = “

”

Matching AS pattern that begins with

(for example, ”_99” matches 99

991 9934)

_ Matching AS pattern that ends with

(for example, “99_” matches 99

199 23299)

Note:

Use the symbols < > and { } only when you want to distinguish between

AS sets and AS sequences.

Table 7-9. Simplified AS Pattern Matching Examples

Command Operation

AS path contains:

ip /jointfilesconvert/99069/bgp_routes -R _555_> Match exactly any occurrence of AS 555 inside any

AS SEQUENCE.

ip /jointfilesconvert/99069/bgp_routes -R _555_} Match exactly any occurrence of AS 555 inside any

AS SET.

ip /jointfilesconvert/99069/bgp_routes -R 555_ Match any AS that begins with 555.

ip /jointfilesconvert/99069/bgp_routes -R 555_ Match any sequence that begins with AS 555.

ip /jointfilesconvert/99069/bgp_routes -R _555_ Match any occurrence of AS 555 inside either an AS

SEQUENCE or an AS SET.

ip /jointfilesconvert/99069/bgp_routes -R <555> Match a sequence containing only 1 AS=555.

ip /jointfilesconvert/99069/bgp_routes -R {555} Match a set containing only 1 AS=555.
