VXLAN Ping/Tracert

VXLAN Ping/Tracert

VXLAN ping/tracert facilitates VXLAN tunnel fault locating because it can test the connectivity, packet loss, and delay on links between devices on VXLANs.

NOTE:

Tracert cannot be used to check the IPv6 VXLAN tunnel.

The CE12800E does not support the IPv6 VXLAN tunnel check using ping.

VXLAN Ping

The following describes the VXLAN ping test process using static IPv4 VXLAN tunnel configuration as an example.

A VXLAN tunnel is specified by a pair of VXLAN Tunnel Endpoint (VTEP) IP addresses. A static VXLAN tunnel can go Up after the VXLAN Network Identifiers (VNIs), IP addresses, and ingress replication lists are configured for the local and remote VTEPs, and there is a reachable Layer 3 routes between the two VTEPs.

On the network shown in Figure 5-32, Server 1 is deployed for Device 1, and Server 2 is deployed for Device 3. To enable communication between VMs on Server 1 and Server 2, configure VNIs and VTEP IP addresses to create a static VXLAN tunnel between Device 1 and Device 3. Device 2 is a forwarding device on the IP network.

Figure 5-32 VXLAN networking diagram
Initiate a VNI-based VXLAN ping test on Device 1 and terminate the ping test on Device 3, as shown in Figure 5-32.
  1. You can initiate a ping test on Device 1 by specifying:
    • VNIs, source VTEP IP address, and peer VTEP IP address.
    • VNIs, source VTEP IP address, peer IP address, and VXLAN source port number.
    • VNIs, source VTEP IP address, peer IP address, and 7-tuple information.
  2. After receiving a ping request packet, Device 3 forwards the packet to the corresponding host based on the inner MAC address. Upon receipt of the packet, the host verifies VNI information and returns a VXLAN reply packet.
  3. Device 1 receives the VXLAN reply packet from Device 3. The ping test is complete.

VXLAN Tracert

Initiate a VNI-based VXLAN tracert test on Device 1 and terminate the tracert test on Device 3 using static VXLAN IPv4 tunnel configuration as an example, as shown in Figure 5-32.
  1. You can initiate a tracert test on Device 1 by specifying:
    • VNIs, source VTEP IP address, and peer VTEP IP address.
    • VNIs, source VTEP IP address, peer IP address, and VXLAN source port number.
    • VNIs, source VTEP IP address, peer IP address, and 7-tuple information.
  2. After receiving a TTL timeout packet, Device 2 replies with an ICMP error packet.
  3. After receiving the ICMP error packet from Device 2, Device 1 adds the TTL value by 1 and continues to send tracert test packets.
  4. After receiving a tracert request packet, Device 3 forwards the packet to the corresponding host based on the inner MAC address. Upon receipt of the packet, the host verifies VNI information and returns a VXLAN reply packet.
  5. Device 1 receives the VXLAN reply packet from Device 3. The tracert test is complete.
