How Can You Differentiate Vpnv4 And Ipv4 Address-family? |
|
Answer» Address-family VPNv4 is used to TRANSPORT VRF TRAFFIC, which is QUITE heavier (96 bits) than normal IPv4 packets, and address-family IPv4 is used to transport traditional 32-bit IPv4 packets. When we deploy L3VPN, we need VPNv4 peering between the PEs to take the VRF routes (labeled with RD, RT) to the corresponding destination PE router.
