What is the difference between BGP and static routing?
Static routes are manually configured and must be manually reconfigured any time the network topology or link status changes. Dynamic BGP provides automatic failover and chooses the optimal path based on the real-time network conditions as well as preset policies.
Is static route preferred over BGP?
Based on BGP route selection rules, the redistributed floating static route will always remain the preferred path if additional BGP configuration is not performed on the provider edge router.
Does a static route override BGP?
General rule of routing: A static route will always override a route learned from a routing protocol (i.e. OSPF, BGP, etc…). Because the customer is not in a BGP session with the Foundry router there are static routes pointing to the customer’s subnets via their cross connected interface.
Is BGP a static routing protocol?
Static routes are the ultimate means of controlling what packets are routed into and out of your network. BGP, or any other type of routing protocol, is unnecessary in this topology.
Is BGP for static or dynamic?
Example of dynamic routing protocols are BGP, EIGRP, OSPF and RIP that you can choose according to your topology, specific requirements ( like scenario: WAN, Internet Edge, Data Center, SP networks), technical capabilities (vendor, type of devices, supported protocols) and so on.
Is static or dynamic routing better?
Static routing provides higher security. Dynamic routing is less secure. Static routing is a manual process. Dynamic routing is an automatic process.
What is floating static route?
Floating static routes are static routes that have an administrative distance greater than the administrative distance of another static route or dynamic routes. They are very useful when providing a backup to a primary link, as shown in Figure 2-66.
Why is BGP preferred over OSPF?
Scale: BGP is more flexible and scalable than OSPF and it is also used on a larger network. Preferred path: OSPF is used to determine the fastest route while BGP puts emphasis on determining the best path. Protocol: In OSPF, internet protocol is used. While in BGP, transmission control protocol is used.
When would you use static route?
Static routing can be used for small networks that require only one or two routes. This is often more efficient since a link is not being wasted by exchanging dynamic routing information. Static routing is often used as a complement to dynamic routing to provide a failsafe backup if a dynamic route is unavailable.
Should I change the default BGP prefix?
You may decide to keep the BGP default prefix as is if you need (to achieve a redundant internet path) just incase if the local internet goes down, it prefers the BGP learnt default route & route via MPLS.
Why are there two additional static routes for eBGP?
If this is the case, the two additional static routes (192.168.0.0/16 and 172.20.0.0/16) are one of the few options to get it to work. They could also have the router that currently originates the default route in the MPLS cloud to also originate these two additional routes so they are received dynamically via eBGP on the local router.
What is the purpose of adding a static route to router?
When they installed the internet on the local router, and added the static route on the router to hit the internet, they need to add the static route (2nd one) to communicate to the other sites. They want to route all the traffic out thru the local intenet besides their private networks ( 192.168.0.0/16 and 172.20.0.0/16).
