I hv attached a rough network dia to understand any alternate way to configured EIGRP with Transparent lan service ( TLS ).
We hv core location as mentioned as R1 & other remote location R3,R4,R5,56 with their repective network( ip's mentioned in dia). All the remote location has a backup FR link to core through R2.
R1- 100 Mbps port
R3,R4,R5,R6 - 10 Mbps port
EIGRP has been used as routing protocol and all the remote location to be access core through TLS and FR should be the back.
I hv configured EIGRP as remote location as mentioned and also at core. Vlan 10 is acting as a transit vlan for all remote location. so all remote location talks to core through vlan 10 transit vlan.
The issue with this is since we put 10.0.1.0 0.0.0.0.255 in eigrp domain all the remote location establish the neighbour relation along with core location having 100 Mbps port. As per the hello and hold interval they try to maintain neigbour relationship.
But it also goes through a frequent EIGRP recalcuation as the hold time expires disrupting the network. I tried to increase the hello and hold time but still it goes through recalculation but the frequecy reduce. Definately there seems not be any issue with TLS but this happen of the TLS broadcast(layer 2) domain. Core port is 100 Mbps and each remote location port is 10 Mbps
Is there any better way to configure EIGRP as there is no possibility I can change much at core location...
Can the direct neighbour statement to 10.0.1.1 at remote R3,R4,R5,R6 can solve for frequent recalcuation ??? What can be an impact on remote location and core side
Need ur help ..
