Problem Effects

All of the listed clients will see one of their two BGP sessions with AS1213 go
down during reload. As we will only reload one at a time, you should not see a
loss of connectivity. You will need to verify you are receiving 2 default
routes on your routers form AS 1213, to ensure connectivity: sh ip bgp 0.0.0.0
[Cisco] show route protocol bgp 0.0.0.0/0 [JunOS] $user@$router> sh ip bgp
0.0.0.0 BGP routing table entry for 0.0.0.0/0 Paths: 2 available 1213
