Forward error correction on VPN overlay networks

This topic shows an SD-WAN with forward error correction (FEC) on VPN overlay networks. FEC is a technique used to control and correct errors in data transmission by sending redundant data across the VPN. It uses six parameters in IPsec phase1/phase1-interface settings:

fec-ingress

Enable/disable Forward Error Correction for ingress IPsec traffic (default = disable).

fec-egress

Enable/disable Forward Error Correction for egress IPsec traffic (default = disable).

fec-base
