Configure TRACK to Link with SLA

Network Requirement

• TRACK links with SLA. Judge the validity of the static route on Device1 via the entity status.

Network Topology

Figure 3–7 Networking of configuring TRACK to link with SLA

Configuration Steps

Step 1: Configure VLAN and add the port to the corresponding VLAN. (Omitted)

Step 2: Configure the IP address of the interface. (Omitted)

Step 3: Configure the ICMP-echo entity on Device1 to detect the network connectivity from Device1 to Device2, and add the entity to the entity group.

#Configure Device1.

Step 4: Define TRACK and associate with LSA.

#Configure Device1.

Step 5: Add the static route and associate TRACK.

#Configure Device1.

Step 6: Schedule the entity and check the validity of the static route.

#Configure Device1.

Step 7: Check the result.

1. When the network connectivity from Device1 to Device2 is normal:

#View the entity group status.

Device1#show rtr group 1 
-----------------------------------------------------------
ID:1            name:rtrGroup1    Members schedule interval:0
Option: AND     Status:REACHABLE 
*****************************
type:SINGLE     Entity Id :1 

The status of the entity group is REACHEABLE.

#In the route table of Device1, view the route of the segment 192.0.0.0/24.

Device1#show ip route 192.0.0.0 
Codes: C - connected, S - static, R - RIP, O - OSPF, OE-OSPF External, M - Management 
       D - Redirect, E - IRMP, EX - IRMP external, o - SNSP, B - BGP, i-ISIS  
 
Gateway of last resort is not set 
 
S	192.0.0.0/24 [1/10] via 110.1.0.2, 00:00:09, vlan2 

The result displays that there is the route to the segment 192.0.0.0/24, indicates that when the status of the entity group is RECHABLE, judge that the static route is valid.

2. When the network connectivity from Device1 to Device2 is faulty:

#View the status of the entity group:

Device1#show rtr group 1 
------------------------------------------------------------
ID:1            name:rtrGroup1      Members schedule interval:0
Option: AND     Status:UNREACHABLE 
*****************************
type:SINGLE     Entity Id :1

The status of the entity group is UNREACHEABLE.

#In the route table of Device1, view the route of the segment 192.0.0.0/24.

Device1#show ip route 192.0.0.2 
Codes: C - connected, S - static, R - RIP, O - OSPF, OE-OSPF External, M Management 
       D - Redirect, E - IRMP, EX - IRMP external, o - SNSP, B BGP, i-ISIS  
 
 
Gateway of last resort is not set 

The result displays that there is no route to the segment 192.0.0.0/24, indicates that when the status of the entity group is UNREACHABLE, judge that the static route is invalid.
