The command output shows that Router E selects the route learned from Router A because the
AIGP attribute has not been configured and the router ID of Router A is smaller than that of
Router B. To change the route selection on Router E, perform the following operations to
configure the AIGP attribute.
Configurations on Router A:
#
bgp 65002
