BGP Failover problem. EEM

Goodday I've a BGP failover proble with EEM.

I've a track icmp object - It's a  ISP BGP peer

track 2 ip sla 2 reachability

ip sla 2

icmp-echo 10.10.10.9 source-interface FastEthernet0/0/0

frequency 5

router bgp 65003

no bgp fast-external-fallover

bgp log-neighbor-changes

neighbor 10.10.10.9 remote-as 65001

neighbor 172.16.1.1 remote-as 65002

!

address-family ipv4

*****

  neighbor 10.10.10.9 activate

  neighbor 10.10.10.9 soft-reconfiguration inbound

  neighbor 172.16.1.1 activate

  neighbor 172.16.1.1 soft-reconfiguration inbound

exit-address-family

event manager applet BGP_ISP_1

event track 2 state down

action 2.0 cli command "enable"

action 2.1 cli command "config t"

action 2.2 cli command "router bgp 65003"

action 2.3 cli command "neighbor 10.10.10.9 shutdown"

event manager applet BGP_ISP_1_UP

event track 2 state up

action 2.0 cli command "enable"

action 2.1 cli command "config t"

action 2.2 cli command "router bgp 65003"

action 2.3 cli command "no neighbor 10.10.10.9 shutdown"

So, when 1 ping fails to ISP_1, eem automatically drops neighborship to ISP_1, but when ISP_1 comes back eem should again activate ISP neighbor, but it didnt do it and in configuration i have

****

router bgp 65003

neighbor 10.10.10.9 shutdown

****

Here is history eem

6    7      Actv abort    Wed Apr24 02:01:18 2013  track              applet: BGP_ISP_1_UP

7    6      Actv abort    Wed Apr24 02:01:13 2013  track              applet: BGP_ISP_1

I think problem is in ip sla? May be i should change frequency and number of retries?

Hello Dmitri,

Why do you need to shut BGP peer if ping fails? There are other ways to speed up BGP convergence if this is your motivation.

Best Regards
