What is TCAM on a router?

What is TCAM on a router?

TCAM (ternary content-addressable memory) is a specialized type of high-speed memory that searches its entire contents in a single clock cycle.

What is TCAM utilization?

TCAM Utilization. TCAM holds the rules produced by applications, such as ACLs (Access Control Lists), Quality of Service (QoS), while Router TCAM holds the rules for IP Routing and user-created rules. Some applications allocate rules upon their initiation.

What is FIB networking?

A forwarding information base (FIB), also known as a forwarding table or MAC table, is most commonly used in network bridging, routing, and similar functions to find the proper output network interface controller to which the input interface should forward a packet.

How do ACI contracts work?

What is a contract inside ACI? Contracts are used to control traffic flow within the ACI fabric between EPGs. Configured between EPGs, or between EPGs and L3out. Contracts are assigned a scope of Global, Tenant, VRF, or Application Profile, which limit the accessibility of the contract.

How do I set up a vzAny contract?

Select the contract you created in Create Contract and Filters, on page 3. c) Select the Contract type. You can choose either consumer or provider for the contract based on your use case. You can choose to create new or use existing EPGs for your vzAny use cases.

What is difference between RIB and FIB?

Each FIB is programmed by one or more routing information bases (RIB). The RIB is a selection of routing information learned via static definition or a dynamic routing protocol.

What is an FIB vs RIB?

RIB: This is a routing protocols database of routing prefixes that could potentially be installed in the routing table. FIB: This is one of two components that make up CEF. The FIB is a mirror copy of the routing table. The other component is the adjacency table which contains next hop L2 information.

What is RIB vs FIB?

What is CEF in Mpls?

CEF is the fundamental switching path for MPLS. Without CEF, MPLS forwarding does not occur. MPLS forwarding relies heavily on the IP routing table and the CEF architecture. Therefore, MPLS VPN relies on CEF because MPLS VPN depends on MPLS for successful operation.

What is ACI bridge domain?

A Bridge Domain (BD) is a Layer 2 representation inside the ACI fabric. The BD is where users will define their Anycast Gateway/subnet which would provide the default gateway for their host attached to the fabric.
