EVPN MPLS Virtual Private Wire Service (VPWS)

Description EVPN MPLS VPWS (RFC 8214) provides the ability to forward customer traffic to / from a given attachment circuit (AC) without any MAC lookup / learning.  The basic advantage of VPWS over an L2 EVPN is the reduced control plane signalling due to not exchanging MAC address information.  In contrast to LDP pseudowires, EVPN MPLS VPWS uses BGP for signalling.  Port based and VLAN based services are supported. VLAN Based Service Port Based Service Platform compatibility DCS-7280R DCS-7280R2 DCS-7280R3 DCS-7500R DCS-7500R2 DCS-7500R3 DCS-7800R3 Configuration VPWS configuration is made up of two main components on each participating router.  The first...

MPLS Tunnel Support for Traceroute and PMTU Discovery

Description IP traceroute and path MTU (PMTU) discovery both require that routers send ICMP reply messages to the host that invokes each network function.  When the route to the destination host traverses an MPLS label-switched path (LSP), the label switching routers (LSRs) will also need to send ICMP reply messages to the originating host. The MPLS ICMP tunneling feature enables these LSRs to generate ICMP reply messages and deliver them to the originating host using the same LSP on which the frame was received.  Once the frame exits the LSP, it is assumed that the ICMP reply can be routed...

Disable IEEE reserved frame trapping

IEEE802.1D-2004, Section 7.12.6 specifies destination MAC addresses that are normally trapped (not forwarded) by the a switch. Starting in version 4.15.0F, EOS allows for frame trapping to be disabled for specific addresses (except STP BPDUs and pause frames). Configuration This feature is currently supported on: DCS-7150 DCS-7010 DCS-7050 DCS-7250 DCS-7300 The CLI configuration is available from the global configuration mode: Arista(config)#mac address-table reserved forward <MAC address or range> By default, all reserved addresses are trapped.  MAC address values specified with this configuration will be forwarded instead.  The possible values for <MAC address or range> depend on the specific platform as shown...
