The value of vRtrRsvpGeneralRefreshBypass specifies whether the
refresh reduction capabilities over all bypass tunnels originating
on the PLR node is enabled. Since a bypass tunnel may merge with
the primary LSP path in a node downstream of the next-hop, there
is no direct interface between the PLR and the MP node and it is
possible that the latter will not accept summary refresh messages
received over the bypass.
When the value of vRtrRsvpGeneralRefreshBypass is 'false', the
summary refresh messages on the node for all primary LSPs over
the bypass tunnels they are associated with, is disabled.
