Does OSPF support ECMP?
The ECMP feature allows OSPF to add routes with multiple next-hop addresses and with equal costs to a given destination in the forwarding information base (FIB) on the routing switch.
What is NSSA in OSPF?
The OSPFv2 not-so-stubby area (NSSA) enables you to configure OSPFv2 areas that provide the benefits of stub areas, but that also are capable of importing external route information.
What is ECMP in Cisco?
Equal Cost Multi-Path or ECMP is a routing strategy where packets towards a single destination IP address are load-balanced over multiple best paths with equal metrics.
Is OSPF do load balancing?
Like other dynamic routing protocols, OSPF does equal cost load balancing, and if you have routes with equal cost paths to the same destination, then OSPF will do load sharing. Unlike Enhanced Interior Gateway Routing Protocol (EIGRP), OSPF can’t do unequal cost load balancing.
What is Ecmp protocol?
Equal-cost multipath (ECMP) is a network routing strategy that allows for traffic of the same session, or flow—that is, traffic with the same source and destination—to be transmitted across multiple paths of equal cost.
What is NSSA no summary?
no-summaries—Prevents the ABR from advertising summary routes into the NSSA. If configured in combination with the default-metric statement, the NSSA only allows routes internal to the area and advertises the default route into the area.
What is Ecmp hashing?
For ECMP, the hashing algorithm determines how incoming traffic is forwarded to the next-hop device. The packet fields used by the hashing algorithm varies by the packet’s EtherType and, in some instances, by the configuration on the switch. The hashing algorithm recognizes the following EtherTypes: IP (IPv4 and IPv6)
