Virtual Private Routed Network Services

interval seconds — This optional parameter specifies the interval between ICMP pings to the target
IP address.
Values 1 —255 seconds
Default 1 seconds
drop-count count — This optional parameter specifies the number of consecutive ping-replies that
must be missed to declare the CPE down and to de-active the associated static route.
Values Value range: 1 —255
Default 3
log — This optional parameter enables the ability to log transitions between active and in-active
based on the CPE connectivity check. Events should be sent to the system log, syslog and SNMP
traps.
next-hop [ip-address | ip-int-name] — Specifies the directly connected next hop IP address used to
reach the destination. If the next hop is over an unnumbered interface, the ip-int-name of the
unnumbered interface (on this node) can be configured.
The next-hop keyword and the indirect or black-hole keywords are mutually exclusive. If an
identical command is entered (with the exception of either the indirect or black-hole
parameters), then this static route will be replaced with the newly entered command, and unless
specified, the respective defaults for preference and metric will be applied.
The ip-addr configured here can be either on the network side or the access side on this node.
This address must be associated with a network directly connected to a network configured on
this node.
ipsec-tunnel ipsec-tunnel-name — specifies an IPSec tunnel name up to 32 characters in length.
indirect ip-address — Specifies that the route is indirect and specifies the next hop IP address used to
reach the destination.
The configured ip-addr is not directly connected to a network configured on this node. The
destination can be reachable via multiple paths. The static route remains valid as long as the
address configured as the indirect address remains a valid entry in the routing table. Indirect
static routes cannot use an ip-prefix/mask to another indirect static route.
The indirect keyword and the next-hop or black-hole keywords are mutually exclusive. If an
identical command is entered (with the exception of either the next-hop or black-hole
parameters), then this static route will be replaced with the newly entered command and unless
specified the respective defaults for preference and metric will be applied.
The ip-addr configured can be either on the network or the access side and is normally at least
one hop away from this node.
black-hole — Specifies a black hole route meaning that if the destination address on a packet
matches this static route it will be silently discarded.
The black-hole keyword is mutually exclusive with either the next-hop or
indirect keywords. If
an identical command is entered, with exception of either the next-hop or indirect parameters,
then the static route is replaced with the new command, and unless specified, the respective
defaults for preference and metric are applied.
