Dear Mr McNamara, Hope youre ok.
I´m writing because i´m litle bit confusing about OSPF Balancing, the escenario that i have is the following:
I have a Branch Office which has conection to the HQ through two differents ISP , in that office i just have one router which receive the two ISP Links , also in the HQ i just have a Main Router for the Links.
In the office´s Router i have made an OSPF configuration to allow conectivity to the HQ, below the OSPF detailed:
interface Tunnel0
ip address 10.10.8.2 255.255.255.252
ip tcp adjust-mss 1400
ip ospf cost 10
keepalive 15 3
tunnel source GigabitEthernet0/0
tunnel destination 10.8.19.130
interface GigabitEthernet0/0
description ***WAN ISP_1***
bandwidth 5000
ip address 172.31.8.2 255.255.255.252
ip flow ingress
ip flow egress
no ip route-cache cef
ip tcp adjust-mss 1400
ip ospf priority 250
ip ospf cost 10
load-interval 60
duplex auto
speed auto
service-policy output WANQoS
interface GigabitEthernet0/0/0
description ***WAN ISP_2***
switchport access vlan 2467
bandwidth 5000
no ip address
load-interval 60
duplex full
speed 100
interface Vlan2467
bandwidth 5000
ip address 172.16.8.2 255.255.255.252
ip nbar protocol-discovery ipv4
ip flow ingress
ip flow egress
ip ospf priority 150
ip ospf cost 15
load-interval 60
service-policy output WANQoS-Telecarrier
router ospf 8
passive-interface GigabitEthernet0/1
network 10.10.8.0 0.0.0.3 area 0
network 172.16.8.0 0.0.0.3 area 0
network 172.31.8.0 0.0.0.3 area 0
network 192.168.8.0 0.0.0.255 area 0
Right now the Office´s Router has two adjacencies with the same router on HQ,
R2901_LosPueblos#show ip ospf neighbor
Neighbor ID Pri State Dead Time Address Interface
10.159.0.1 150 FULL/BDR 00:00:34 172.16.8.1 Vlan2467
10.159.0.1 0 FULL/ - 00:00:35 10.10.8.1 Tunnel0
R2901_LosPueblos#
The Question is if i need to send some traffic through the ISP_1 and other through ISP_2 who could i fix that, because rigth now the whole traffic is leaving from the office through ISP_2, i dont undestarnd why, if ISP_2 has a highest cost than ISP1, also i have noticed that the the OSPF network type for ISP_1 is Point to Point and for ISP_2 is Broadcast, that cause a faster convergencie time for ISP1 but i dont know if that influency on the network routing.
Will appreciate if you can help me with my doubt.
Best Regards.
