HI guys . I have routers 1861 configured with eigrp to local cable ISP(A) and ospf to mpls another ISP carrier (B) . We have Exchange server in central site , so all sites users connect to it trough vpn (either ipsec to local ISP A or mpls vpn to B ). some sites can not connect to Exchange server .
When I did research I see : OSPF take priority
#sho ip route 10.x.x.x Routing entry for x.x.x.x Known via "ospf 100", distance 110, metric 20, type extern 2, forward metric 32 Last update from a.a.a.a on FastEthernet0/0, 00:36:59 ago Routing Descriptor Blocks: * a.a.a.a, from a.a.a.a, 00:36:59 ago, via FastEthernet0/0 Route metric is 20, traffic share count is 1 although we have eigrp with AD 90 . When i turn off fa0/0 ip route goes trough eigrp(cable internet) but when i turn on it back to ospf (mpls).
sho ip route eigrp :
10.0.0.0/8 is variably subnetted, 422 subnets, 9 masks D 10.0.0.0/8 [90/26880256] via y.y.y.y, 01:03:34, Tunnel252
sho ip route ospf :
10.0.0.0/8 is variably subnetted, 422 subnets, 9 masks O E2 10.1.0.0/27 [110/20] via z.z.z.z, 01:07:00, FastEthernet0/0
why ?? only difference i see that may cause trough ospf route entry is more explicit ... But router must choose eigrp with AD 90 not ospf with AD110 , right ?
Can ISP manipulate with tcp/udp ports on MPLS link to open/close services, control layer 7 ?
I can telnet to Exchange server ports from that router,can ping by ip trough mpls, but I can't ping exchange server by name . I spoke with ISP they don't have any policy or inspect on ports . So, I am thinking maybe the thing that no name resolution cause that issue when users cannot connect to Exchange ?
This is actually a pretty cool feature, i didn't even know it existed until I was looking for a solution to advertise a subnet (prefix in BGP talk), only if a certain condition existed. This is exactly what conditional advertisements does
