Can you load balance over two static route connections?
How it works? If you have two routers / two Layer3 switches connected with two L3 links (two paths) you can route with two equal static routes towards the same prefix and the router will load balance traffic across both links. The idea is to make two same static routes on the same router but with different next-hops.
Does BGP load balance by default?
By default, Border Gateway Protocol (BGP) selects only a single best path and does not perform load balancing.
Does OSPF load balance by default?
OSPF load balances across equal cost paths to the same destination by default. If the destination is connected to R1 then R2 will never load balance across the direct path to R1 and the indirect path through R3 because they are not equal cost.
Can you use load balancing with static routes?
If an enterprise network has two egresses, two equal-cost static routes can be configured for load balancing. In this case, two non-equal-cost static routes can be configured for active/standby backup.
When to use per destination or per destination load balancing?
Per-destination load balancing is enabled by default when you enable Cisco Express Forwarding, and it is the load balancing method of choice for most situations. Because per-destination load balancing depends on the statistical distribution of traffic, load sharing becomes more effective as the number of source-destination pairs increase.
Which is the default routing algorithm for load balancers?
The default routing algorithm is round robin. Routing is performed independently for each target group, even when a target is registered with multiple target groups. With Network Load Balancers, the load balancer node that receives the connection uses the following process:
How does per packet load balancing work on a router?
Per-packet load balancing allows the router to send successive data packets over paths without regard to individual hosts or user sessions. It uses the round-robin method to determine which path each packet takes to the destination. Per-packet load balancing ensures balancing over multiple links.
When to use load balancing over parallel links?
Software implements Layer 3 load balancing across multiple parallel links when using Cisco Express Forwarding. This document assumes an understanding of the two data structures of Cisco Express Forwarding. See the “Related Information” section of this document for a Cisco Express Forwarding overview of operation.
