Thanks Howard,
No matter I activated "bgp detereministic-med" it still choose the
confed-internal route, as shown as following:
R8#sh ip b 10.26.1.0
BGP routing table entry for 10.26.1.0/24, version 11
Paths: (2 available, best #1, table Default-IP-Routing-Table)
Advertised to non peer-group peers:
172.16.1.26
(26)
172.16.1.26 (metric 97) from 172.16.1.5 (172.16.1.5)
Origin IGP, metric 0, localpref 100, valid, confed-internal, best
(26)
172.16.1.26 (metric 97) from 172.16.1.26 (172.16.1.26)
Origin IGP, metric 0, localpref 100, valid, confed-external
Thx,
BBD (Big Black Dog)

Do you have BGP deterministic-med coded on the interfaces in
question? It often clears obscure problems like this.
