Static route gateway X.X.X.X is not directly connected via an interface
Hello, When verifying bigip.conf file, an error is reported about a network route. But the error has no reason to be there. Here is the error: &&&&&&&&&&& load sys conf file /config/bigip.conf verify Validating system configuration... . . Validating configuration... /config/bigip.conf 01070330:3: Static route gateway 10.10.99.254 is not directly connected via an interface.

Gateway Failsafe and default gateways
Hi, I am quite lost concerning how Gateway Failsafe (GF) can be used to monitor def GW in cluster. Def GW object is object synced between nodes. So I can't see a way to set two different Def GW on nodes. GF is based on monitoring two different gateways (or other objects). Each device have to use completely separate (separate Pool with separate pool members like: DeviceA - gf1_pool - 10.10.10.1:0 DeviceB - gf2_pool - 10.10.11.1:0 It makes sense because in case of Failover based on GF new Active should have it's pool UP. If it would be the same device then most probably it would be Down same as on Active. Sure, both devices can have different network paths to the same device but probably it's less frequent. Maybe that is because of name used for this feature that suggested me that it can be used to monitor Def GW, but in fact it's not at all? The final question is if there is a way to have separate Def GW per node in cluster? I mean using Routes config, not magic with VSs? And can GF be used to actually monitor access to Internet from nodes - via separate gateways? Piotr
Big-ip default route - rule of thumb?
I'm wondering if there's a "rule of thumb" for configuring a default route, ie. which network to use if there's just one. For example, a 2200 with... Management access: 192.168.10.0 Vservers:192.168.110.0 Backend networks:192.168.20.0, 192.168.30.0 and 192.168.40.0 (assume all use a /24 mask) Thus in this scenario, which network should I use for my default route? I've seen some articles about configuring multiple routes, but no "best practice" if there's only one. Thanks!
Do I need a "Route" configured for route domain 0?
Hi all, I'm currrently using route domain 0 for everything on the Big-IP. I've not created any other route domains. When I go to Network > Routes, there are no routes listed. Do I need to create a default route for route domain 0? What does route domain 0 use as its default route if I don't specify one?Default Route into OSPF
I am unable to advertise a default route 0.0.0.0/0 from the F5 into ospf. I have an F5 VE running 12.1.1 on KVM-QEMU. IMI is running and I have neighbor relationships with the appropriate routers. All other routes that I test are added without issues, but I do not see the 0.0.0.0/0 route being advertised into ospf.

Hi, Please I need assistance with this issue. I created a default route of 0.0.0.0/24 to 10.221.75.2 but traffic is not being directed to the. However, a route of 4.2.2.2 forwarded traffic to the same IP. What might the problem be? My colleague asked if F5 understands route 0.0.0.0?? Please I need this urgently. Thank youCluster Cross subnet
Hi, We currently have two independent clusters of F5 in separate subnets (sites) and require a method for synchronizing the configuration between them. There is a restriction on the deployment where they must be in separate subnets. The two sites run active-active. The obvious issue for this is that the gateways are separate and when we attempt to synchronize the configuration, the gateway address is clobbered, resulting in the routing breaking. We've tried a few things including: sync only; doesn't synchronize everything ip gw pool w/ sync fail-over; server split routing looking at the files manually and syncing them with external script Does anybody have advice on how they would handle this situation? Thanks.Gateway Failsafe and default gateways
