Path cost from this bridge to the CIST root as seen across MST region boundaries; used together with rcMstpXstInternalRootCost to reconstruct the full path cost to the root.
Examples
Walk all instances (SNMPv2c):
snmpwalk -v2c -c public <target> 1.3.6.1.4.1.8886.6.1.24.2.12 snmpwalk -v2c -c public <target> SWITCH-MSTP-MIB::rcMstpBridgeCistExternalRootCost
Get a specific instance (index 1):
snmpget -v2c -c public <target> 1.3.6.1.4.1.8886.6.1.24.2.12.1 snmpget -v2c -c public <target> SWITCH-MSTP-MIB::rcMstpBridgeCistExternalRootCost.1
SNMPv3 example:
snmpget -v3 -l authPriv -u snmpv3-user -a SHA -A "AuthPassword1" -x AES -X "PrivPassword1" <target> rcMstpBridgeCistExternalRootCost.1
