DEPI Downstream PW UEPI Upstream PW DEPI Local MTU AVP (ICRQ) UEPI Local MTU AVP (ICRQ).

What is docsRphyRpdDevL2tpSessionInfoCoreIfMtu?

Reports the CCAP Core's CIN interface MTU, read from the Local MTU AVP the Core sent during L2TPv3 session setup (ICRQ message). Operators compare this against the RPD's own interface MTU to detect an MTU mismatch between the two session endpoints.
