RIP Route Entry Class.
This class is used for storing RIPv2 and RIPng route entries. It is a template class taking an address family type as a template argument. Only IPv4 and IPv6 types may be supplied.
| typedef A Addr | Addr | 
| typedef IPNet<A> Net | Net | 
| typedef RouteEntryOrigin<A> Origin | Origin | 
| RouteEntry (const Net&  n,
	       const Addr& nh,
	       uint16_t	   cost,
	       Origin*&	   o,
	       uint16_t    tag) | RouteEntry | 
Constructor.
The constructor set the internal state according to the parameters and if the Origin is non-null makes the appropriate call to tell the Origin of it's existence.
| RouteEntry (const Net&  n,
	       const Addr& nh,
	       uint16_t	   cost,
	       Origin*&	   o,

| ~RouteEntry () | ~RouteEntry | 
Destructor.
Cleans up state associated with RouteEntry. If the Origin associated with the RouteEntry is not-null, the Origin is informed of the destruction.
| inline const IPNet<A>&  net () | net | 
[const]
| bool  set_nexthop (const A& nh) | set_nexthop | 
Set next hop.
Parameters:
| nh | the new nexthop to be associated with Route Entry. | 
Returns: true if the stored nexthop changed, false otherwise.
| inline const A&  nexthop () | nexthop | 
[const]
Get next hop.
Returns: nexthop address associated with the route entry.
| bool  set_cost (uint16_t cost) | set_cost | 
Set the cost metric.
Parameters:
| cost | the new cost to be associated with the Route Entry. | 
Returns: true if stored cost changed, false otherwise.
| uint16_t  cost () | cost | 
[const]
Get the cost metric.
Returns: the cost associated with the route entry.
| bool  set_origin (Origin* origin) | set_origin | 
Set the origin. If the origin is different from the stored origin, the RouteEntry dissociates itself from the current origin and informs the new origin of it's existence.
Parameters:
| origin | the new origin to be associated with the route entry. | 
Returns: true if the stored origin changed, false otherwise.
| inline const Origin*  origin () | origin | 
[const]
Get the origin.
Returns: a pointer to the origin associated with the route entry.
| inline Origin*  origin () | origin | 
Get the origin.
Returns: a pointer to the origin associated with the route entry.
| bool  set_tag (uint16_t tag) | set_tag | 
Set the tag value.
Parameters:
| tag | the tag value to be associated with the route entry. | 
Returns: true if the stored tag changed, false otherwise.
| inline uint16_t  tag () | tag | 
[const]
Get the tag.
Returns: tag value associated with the route entry.
| inline void  set_timer (const XorpTimer& t) | set_timer | 
Set a Timer Event associated with this route.
| inline const XorpTimer&  timer () | timer | 
[const]
Get Timer associated with route.
| const PolicyTags&  policytags () | policytags | 
[const]
Returns: policy-tags associated with route.
| bool  set_policytags (const PolicyTags& tags) | set_policytags | 
Replace policy-tags of route
Parameters:
| tags | new policy-tags. | 
Returns: true if tags were modified.
| bool  filtered () | filtered | 
[const]
Returns: true if route was rejected by policy filter.
| void  set_filtered (bool v) | set_filtered | 
Set if route is accepted or rejected.
Parameters:
| v | true if route is filtered |
