rlOspfNetLnkLength
Module: CISCOSB-IpRouter
OID (symbolic): CISCOSB-IpRouter::rlOspfNetLnkLength
OID (numeric): 1.3.6.1.4.1.9.6.1.101.26.14.5.1.8
Node type: OBJECT-TYPE
Type: Unsigned32
Access: read-only
Description: The lenth in bytes of the LSA. This includes the 20 byte LSA header.
What is rlOspfNetLnkLength?
This read-only Unsigned32 gives the byte length of the Network-LSA, including its fixed 20-byte header. Because the LSA body lists every router attached to the network, this length grows as more routers join that broadcast segment, letting an admin gauge segment size without decoding the LSA. For example, watching this length increase after cabling three new routers onto a shared VLAN confirms OSPF has appended their entries to the Network-LSA.
