BGP per Neighbor SoO Configuration |
12.2(33)SB 12.2(33)SRB 12.4(11)T 15.0(1)SY |
The BGP per neighbor SOO configuration feature simplifies the configuration of the site-of-origin (SoO) parameter. In Cisco IOS Release 12.4(9)T, 12.2(33)SRA, 12.2(31)SB2, and previous releases, the SoO parameter is configured using an inbound route map that sets the SoO value during the update process. The per neighbor SoO configuration introduces two new commands that can be configured in submodes under router configuration mode to set the SoO value. The following commands were introduced by this feature: neighbor soo, soo. |
BGP Support for 4-Byte ASN |
12.0(32)S12 12.0(32)SY8 12.2(33)SRE 12.2(33)XNE 12.4(24)T |
The BGP Support for 4-Byte ASN feature introduced support for 4-byte autonomous system numbers. Because of increased demand for autonomous system numbers, in January 2009 the IANA will start to allocate 4-byte autonomous system numbers in the range from 65536 to 4294967295. In Cisco IOS Release 12.0(32)SY8, 12.2(33)SRE, and 12.2(33)XNE, the Cisco implementation of 4-byte autonomous system numbers uses asplain as the default regular expression match and output display format for autonomous system numbers, but you can configure 4-byte autonomous system numbers in both the asplain format and the asdot format as described in RFC 5396. To change the default regular expression match and output display of 4-byte autonomous system numbers to asdot format, use the bgp asnotation dot command. In Cisco IOS Release 12.0(32)S12, and 12.4(24)T, the Cisco implementation of 4-byte autonomous system numbers uses asdot as the only configuration format, regular expression match, and output display, with no asplain support. The following commands were modified by this feature: bgp asnotation dot, bgp confederation identifier, bgp confederation peers, clear ip bgp, ip bgp-community new-format, ip extcommunity-list, match source-protocol, neighbor local-as, neighbor remote-as, neighbor soo, redistribute (IP), router bgp, set as-path, set extcommunity, set origin, soo, and all show ip bgp commands that display an autonomous system number. |
