Redistribute routes
In addition to filtering routes, you can add routes from other routing instances or protocols to the BGP
process. With the
redistribute
command syntax, you can include ISIS, OSPF, static, or directly connected
routes in the BGP process.
Use any of the following commands in ROUTER BGP mode to add routes from other routing instances or
protocols.
( ) (parenthesis) Specifies patterns for multiple use when followed by one of the multiplier metacharacters:
asterisk *, plus sign +, or question mark ?
[ ] (brackets) Matches any enclosed character; specifies a range of single characters
- (hyphen) Used within brackets to specify a range of AS or community numbers.
_ (underscore) Matches a ^, a $, a comma, a space, a {, or a }. Placed on either side of a string to specify a
literal and disallow substring matching. Numerals enclosed by underscores can be preceded or
followed by any of the characters listed above.
| (pipe) Matches characters on either side of the metacharacter; logical OR.
