Overview

Fast Path GRE provides IPvX and Ethernet over GRE support in the fast path.

Features

  • Supported features:

    • IPv4 over IPv4 GRE tunnelling (L3 tunnel)

    • IPv6 over IPv4 GRE tunnelling (L3 tunnel)

    • IPv6 over IPv6 GRE tunnelling (L3 tunnel)

    • IPv4 over IPv6 GRE tunnelling (L3 tunnel)

    • IPV4 over Ether GRE tunnelling (L2 tunnel)

    • IPV6 over Ether GRE tunnelling (L2 tunnel)

  • Ethernet GRE can be encapsulated on IPv4 (gretap) or IPv6 (ip6gretap)

  • Cross-VRF processing (the encapsulated and plaintext traffic may be in different VRFs, the GRE interface performs the VRF transition).
