Thanks. The EIGRP Convergence is slow. Before it was fast but now it's slow. Although we have tunnel2 for those routes. Here are the configuration for Tunnel The bandwidth of the ISP is 12mb and tunnel bandwidth is configured for 2000. Current configuration : 562 bytes ! interface Tunnel1 description Primary TW1 Data Tunnel bandwidth 2000 ip address 172.18.1.25 255.255.255.0 no ip redirects ip mtu 1400 ip nhrp authentication AUTH@1 ip nhrp map multicast 200.40.170.200 ip nhrp map 172.18.1.2 200.40.170.200 ip nhrp map 172.18.1.1 200.19.169.200 ip nhrp map multicast 200.19.169.200 ip nhrp network-id 63 ip nhrp nhs 172.18.1.1 ip nhrp nhs 172.18.1.2 ip tcp adjust-mss 1360 delay 500 tunnel source GigabitEthernet0/1 tunnel mode gre multipoint tunnel key 63 tunnel protection ipsec profile CoverTunnels end
