Which of the following is true regarding the structure of a VPN ID? (Select the best answer.)
- It begins with a 4-byte VPN index and ends with a 6-byte MAC address.
- It begins with an 8-byte RD and ends with a 4-byte IPv4 address.
- It begins with a 4-byte IPv4 address and ends with a 3-byte OUI.
- It begins with a 3-byte OUI and ends with a 4-byte VPN index.
- It begins with a 6-byte MAC address and ends with a 4-byte IPv4 address.
Explanation:
A virtual private network (VPN) ID begins with a 3byte Organizationally Unique Identifier(OUI) and ends with a 4byte VPN index. The VPN ID identifies a VPN routing and forwarding (VRF). To update a VPN ID for a VRF, issue the vpn id oui: vpn-index command from VRF configuration mode.
Although a Media Access Control (MAC) address contains an OUI, a VPN ID does notcontain a MAC address. A VPN ID also does not contain a route distinguisher (RD) or an
IPv4 address. However, a multiprotocol Border Gateway Protocol (BGP) VPNIPv4 address begins with an 8byte RD and ends with a 4byte IPv4 address.
