Here are two configuration examples, one for a router with two (primary and backup) links, the second for a router with three links. In the second example, the boolean operator in the track list will make sure that when one link is down, the next one will be used, in sequence. It is recommended to add the EEM script as stated, in order to make sure that the NAT entries are immediately cleared.   Example 1:   interface FastEthernet0/0 description ISP Primary ip address 100.100.100.1 255.255.255.252 ! interface FastEthernet0/1 description ISP Backup ip address 200.200.200.1 255.255.255.252 ! ip sla 1 icmp-echo 8.8.8.8 source-interface FastEthernet0/0 timeout 1000 threshold 2 frequency 3 ! ip sla schedule 1 life forever start-time now ! track 1 ip sla 1 reachability ! ip route 0.0.0.0 0.0.0.0 100.100.100.2 track 1 ip route 0.0.0.0 0.0.0.0 200.200.200.2 10 ! event manager applet CLEAR_NAT event track 1 state any action 1.0 cli command “enable” action 2.0 cli command “clear ip nat translation *” action 3.0 cli command "end" ------------------   Example 2:   track 1 ip sla 1 reachability ! track 2 ip sla 2 reachability ! track 3 list boolean or object 1 object 2 ! interface FastEthernet0/0 description ISP Primary ip address 100.100.100.1 255.255.255.252 duplex auto speed auto media-type rj45 ! interface FastEthernet0/1 description ISP Secondary ip address 150.150.150.1 255.255.255.252 duplex auto speed auto media-type rj45 ! interface FastEthernet0/2 ip address 200.200.200.1 255.255.255.252 description ISP Terciary duplex auto speed auto media-type rj45 ! ip route 0.0.0.0 0.0.0.0 100.100.100.2 track 1 ip route 0.0.0.0 0.0.0.0 150.150.150.2 100 track 2 ip route 0.0.0.0 0.0.0.0 200.200.2000.2 200 ! ip sla 1 icmp-echo 8.8.8.8 source-interface FastEthernet0/0 threshold 1000 timeout 3000 frequency 3 ip sla schedule 1 life forever start-time now ip sla 2 icmp-echo 8.8.8.8 source-interface FastEthernet0/1 threshold 1000 timeout 3000 frequency 3 ip sla schedule 2 life forever start-time now ! event manager applet CLEAR_NAT event track 3 state any action 1.0 cli command “enable” action 2.0 cli command “clear ip nat translation *” action 3.0 cli command "end" ...

Hello,   dynamic routing protocols are not a good idea, most ISPs support only BGP anyway, so you are better off using static routes. SLA can track multiple routes, you can build in whatever dependency you need (e.g. route 3 gets activated when BOTH route 1 and route 2 are uanavailable, or when ONLY one of the two is unavailable). Typically you would use a boolean operator to configure this dependency.   ... View more

Hello,   unless you have a 10Gig module installed, a 1 Gig interface will at max line rate 1 Gig of speed. That is why I said you don't need the boost license. Actually, even without any license (performance or boost) you still get 2.5 Gbps througput. If you are sure you won't be getting more than 1 Gig, you don't really need a license at all. ...

Hello,   the boost license  does not require the performance license. The boost license gives you line rate speeds, so if your physical link can handle 10Gig, the boost license will support it. 1Gig, as in your question, is no problem. Actually, if you only need 1Gig, the performance license would be sufficient.   According to the docs, to use the Boost performance license, the device must be running the Cisco IOS XE software version 16.07.01 or later. That means anything higher, inlcuding 16.8/9/10/11 supports it. And anything lower, such as 16.6, does not. ... View more
