The value of vRtrIfIpcpPeerAddrType specifies the type of
vRtrIfIpcpPeerAddr, the remote peer's IP address.
vRtrIfIpcpPeerAddrType can be set to non-default only when the
following rules are met for objects in vRtrIfEntry with the same
indices:
- The value of vRtrIfType is set to serviceIes(3) or serviceVprn(5)
- The value of tmnxPortEncapType in tmnxPortEntry indexed using
the value of vRtrIfPortID is set to unknown (0) or nullEncap (1)
or ipcpEncap (6)
When the value of vRtrIfIpcpPeerAddrType is unknown, the value of
vRtrIfIpcpPeerAddr is assumed to be of size 0.
