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,
uint16_t tag,
const PolicyTags& policytags)
| RouteEntry |
| ~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 |
