ospfPmEntVpnRouteTag

The VPN route tag used for loop detection as part of OSPF
PE-CE protocol function.
              
This field is only used if ospfPmEntVpnPeCeSupport is
true.
              
If this field is set to zero then VPN route tag function
is disabled.
              
VPN route tag function is specified in RFC 4577, and
VPN route tag configuration is described in sections
4.2.5.1 and 4.2.5.2.
              
In particular RFC 4577 sectios 4.2.5.1 and 4.2.5.2 state
the following.
              
- If OSPF PE-CE protocol function is enabled then by
  default a VPN route tag MUST be configured.
              
- If the Autonomous System number of the VPN backbone is
  two bytes long, the VPN route tag SHOULD be set to
  0xD000nnnn where nnnn is the AS number of the VPN
  backbone.
              
- When it is no longer necessary to use the VPN Route Tag
  in a particular deployment, its use (both sending and
  receiving) may be disabled by configuration.
              
If ospfPmEntVpnRouteTag is non-zero then it overrides any
OSPF tag supplied with a redistributed route.
In particular, it overrides any OSPF tag specified by
rtmRedistNwOspfTag in the rtmRedistTable MIB for this OSPF
instance.
