Показать описание
Just an update to address an issue with a video I released in 2021 titled: " How To Configure Dual ISP Failover on a Cisco Router With a Dynamic Public IP Address".

SAMPLE EEM SCRIPTS
---------------------------------------------------

*** REMEMBER TO CHANGE THE BRACKETED INFORMATION (i.e. [WAN2 INTERFACE HERE], etc) WITH YOUR OWN CONFIG ***

EEM Option 1:
---------------------------------------------------
event manager applet SHUT_NOSHUT_ISP1
event syslog pattern "Interface [WAN2 INTERFACE HERE] assigned DHCP address"
action 1.0 cli command "en"
action 2.0 cli command "conf t"
action 3.0 cli command "[WAN1 INTERFACE HERE]"
action 4.0 cli command "shut"
action 5.0 cli command "no shut"
action 6.0 cli command "exit"
action 7.0 cli command "end"

EEM Option 2:
---------------------------------------------------
event manager applet REFRESH_RMAP
event syslog pattern "Interface [WAN2 INTERFACE HERE] assigned DHCP address"
action 1.0 cli command "en"
action 2.0 cli command "conf t"
action 3.0 cli command "no route-map [ROUTE MAP NAME HERE]"
action 4.0 cli command "route-map [ROUTE MAP NAME HERE]"
action 5.0 cli command "match ip address [ACL HERE]"
action 6.0 cli command "set ip next-hop dynamic dhcp"
action 7.0 cli command "set interface [WAN1 INTERFACE HERE] Null0"
action 8.0 cli command "exit"
action 9.0 cli command "end"

Did your setup change for this video from the one before? I believe you used GigabitEthernet0/0 and GigabitEthernet0/1in your previous video, or am I mistaken?
