In the traditional data center design, inter-subnet forwarding is provided by a centralized router, where traffic traverses across the network to a centralized routing node and back again to its final destination. In a large multi-tenant data center environment this operational model can lead to inefficient use of bandwidth and sub-optimal forwarding.

This feature introduces the support for IPv4 ACL configuration under GRE and IPsec tunnel interfaces. The configured ACL rules are applied to a tunnel terminated GRE packet i.e. any IPv4-over-GRE-over-IPv4 that is decapsulated by the GRE tunnel-interface on which the ACL is applied or a packet terminated on IPsec tunnel

This feature implements RFC 5310 that allows IS-IS PDUs to be authenticated using following secure hash algorithms (SHA): SHA-1, SHA-224, SHA-256, SHA-384 and SHA-512. The feature is supported in both default and non-default vrf. Unlike the existing authentication scheme based on MD5 and ClearText, with this feature two IS-IS nodes can be configured with different SHA algorithm and secret-key and can still exchange IS-IS PDUs.

Time stamping is an important tool for network engineering and performance analysis. EOS-4.21.3F adds support for payload timestamping of all GRE encapsulated mirrored packets at line rate (initially only supported on the 7500R/7280R/7500R2/7280R2 series). A timestamp is taken on ingress and inserted into the GRE encapsulated mirrored packet payload at egress.

In conventional VXLAN deployments, each MLAG pair of switches are represented as a common logical VTEP. VXLAN traffic can be decapsulated on either switch. In some networks, there are hosts that are singly connected to one of the MLAG pair.

The ‘show interfaces interactions’ command aims to provide users a resource that explains various relationships between ethernet interfaces. It describes interactions in which a configuration on an interface causes another set of interfaces to become inactive or have reduced capabilities.Examples include a primary interface consuming subordinate interfaces to service a four-lane speed or platform restrictions that require four interfaces of a port to operate at the same speed.
