Cisco router WAN Redundancy/WAN Failover and Change Routing dynamicaly Using IP SLA Redundancy and OSPF Objective: 1. Learn how to connect the routers and switches in a redundant design. 2. Learn how to configure OSPF(Open Shortest Path First) routing. 3. Test to determine whether or not redundant configuration is functioning as designed. Background: 1.

The OSPF router does not, by default, generate a default route into the OSPF domain. In order for OSPF to generate a default route, you must use the default-information originate command. There are two ways to advertise a default route into a normal area. Browse other questions tagged ospf redundancy ieee-802.1s or ask your own question.

-OSPF -BGP • ECMP only works for routes that are sourced by the same routing protocol (i.e: Static Route, OSPF or BGP). • ECMP is enabled by default with 10 paths. • ECMP with static routes is effective if the routes are configured with the same distance and same priority. ECMP Distribution algorithm:

ECMP Distribution algorithm: Link redundancy will be solved by specifying uplink priorities. When the primary link loses connectivity, the secondary wired link will activate the link to the second ISP and the IPSec tunnels can be reestablished through the internet. The following configuration snippet will set up IPSec tunnels and OSPF adjacencies from the remote office. However, both OSPF and EIGRP take more time to recover than some networks can accept. Hot Standby Router Protocol (HSRP) and Virtual Router Redundancy Protocol (VRRP) are available to reduce the amount of time needed to recover from a router failure.

The Overflow Blog Steps Stack Overflow is taking to help fight racism From a redundancy perspective, If you need to think about redundancy only, you don't even need OSPF as such. Static routing with SLAs could help. An easy reference could be this IP SLA on NE. In terms of loops, if you are really interested in understanding how loops could happen in OSPF , read this Loop prevention in OSPF and BGP Loop To configure OSPF with IPsec VPN to achieve network redundancy using the CLI: Configure the WAN interface and static route. Each FortiGate has two WAN interfaces connected to different ISPs. The ISP1 link is for the primary FortiGate and the IPS2 link is for the secondary FortiGate. Personally, It sounds like GLBP is the best because it combines the redundancy that HSRP & VRRP provide, while providing actual load-balancing. Oddly, I’ve read/seen HSRP used much more frequently than GLBP; do you think this is simply because more people are familiar with HSRP/ Cisco pushes it harder or is there a legitimate design reason?
