Hello everyone, I am trying to modify the metric when redistributing connected routes using a route-map. I change the bandwidth value inside the route-map but neighbours still calculate the same value as previous:
R1 and R4 are connected to 192.168.1.0/24
R1
===
router eigrp 1
redistribute connected route-map CONNECTED_INTO_EIGRP1_MAP
network 10.0.0.0 0.0.0.255
auto-summary
route-map CONNECTED_INTO_EIGRP1_MAP permit 10
set metric 100000 1000 255 1 1500
R4
===
router eigrp 1
redistribute connected route-map CONNECTED_INTO_EIGRP1_MAP
network 10.0.0.0 0.0.0.255
auto-summary
route-map CONNECTED_INTO_EIGRP1_MAP permit 10
set metric 50000 1000 255 1 1500
R3
===
R3#show ip route
...
D EX 192.168.1.0/24 [170/27136000] via 10.0.0.4, 00:02:35, Tunnel0
[170/27136000] via 10.0.0.1, 00:02:35, Tunnel0
R3#show ip eigrp topology 192.168.1.0
...
10.0.0.1 (Tunnel0), from 10.0.0.1, Send flag is 0x0
Composite metric is (27136000/281600), Route is External
...
10.0.0.4 (Tunnel0), from 10.0.0.4, Send flag is 0x0
Composite metric is (27136000/307200), Route is External
...
If I change delay value, neighbours calculate a new metric:
R4
===
route-map CONNECTED_INTO_EIGRP1_MAP permit 10
set metric 100000 10 255 1 1500
R3#show ip route
...
D EX 192.168.1.0/24 [170/26882560] via 10.0.0.4, 00:00:35, Tunnel0
R3#show ip eigrp topology 192.168.1.0
...
10.0.0.4 (Tunnel0), from 10.0.0.4, Send flag is 0x0
Composite metric is (26882560/28160), Route is External
...
10.0.0.1 (Tunnel0), from 10.0.0.1, Send flag is 0x0
Composite metric is (27136000/281600), Route is External
...
I studied that EIGRP used bandwitdh and delay to calculate metric. What I am doing wrong ? Am i confusing metric with FD ?
Thanks in advanced.

EIGRP uses the minimum path bandwidth in metric calculation. You're learning routes at R3 via tunnel interfaces. Have you verified the tunnel interface bandwidth setting vs the bandwidth used in your redistribution metric?
