BGPMain& bgp)
| NextHopResolver |
| ~NextHopResolver ()
| ~NextHopResolver |
[virtual]
| void add_decision (DecisionTable<A> *decision)
| add_decision |
Add decision.
Pass a pointer to the decision table into the next hop resolver. This pointer is used to notify the decision table when a next hop metric changes.
Parameters:
| decision | Pointer to the decision table. |
| bool register_ribname (const string& r)
| register_ribname |
Set the rib's name, allows for having a dummy rib or not having a RIB at all.
| bool register_nexthop (A nexthop, IPNet<A> net_from_route,
NhLookupTable<A> *requester)
| register_nexthop |
[virtual]
Register interest in this nexthop.
Parameters:
| nexthop | Nexthop. |
| net_from_route | The net that is associated with this nexthop in the NextHopLookupTable. Treated as an opaque id. |
| requester | Once the registration with the RIB suceeds the requester is called back. |
Returns: True if the registration succeed.
| void deregister_nexthop (A nexthop, IPNet<A> net_from_route,
NhLookupTable<A> *requester)
| deregister_nexthop |
[virtual]
De-Register interest in this nexthop.
Parameters:
| nexthop | Nexthop. |
| net_from_route | The net that is associated with this nexthop in the NextHopLookupTable. Treated as an opaque id. |
| requester | Original requester, not used. |
Returns: True if the registration succeed.
| bool lookup (const A nexthop, bool& resolvable,
uint32_t& metric)
| lookup |
[const virtual]
Lookup next hop.
If a "register_nexthop" request has been made and callback has taken place via the "requester" pointer, then the lookup is guaranteed to work.
Parameters:
| nexthop | Next hop. |
| resolvable | Is this route resolvable. |
| metric | If this route is resolvable the metric of this route. |
Returns: True if this next hop is found.
| bool rib_client_route_info_changed (const A& addr,
const uint32_t& real_prefix_len,
const A& nexthop,
const uint32_t& metric)
| rib_client_route_info_changed |
Call from the RIB to notify us that a metric has changed.
| bool rib_client_route_info_invalid (const A& addr,
const uint32_t& prefix_len)
| rib_client_route_info_invalid |
Call from the RIB to notify us that any registrations with this address and prefix_len are now invalid.
| void next_hop_changed (A nexthop)
| next_hop_changed |
Next hop changed.
Whenever a next hop changes this method should be called and the change will be rippled up to the decision process.
Parameters:
| nexthop | The next hop that has changed. |
| void next_hop_changed (A nexthop, bool old_resolves, uint32_t old_metric)
| next_hop_changed |
Next hop changed.
Whenever a next hop changes this method should be called and the change will be rippled up to the decision process. However if a change occurs but the metrics don't change don't bother to ripple up the change there is no point.
Parameters:
| nexthop | The next hop that has changed. |
| old_resolves | The old resolve value. |
| old_metric | The old metric value. |
| NextHopRibRequest<A> * get_next_hop_rib_request ()
| get_next_hop_rib_request |
Get NextHopRibRequest pointer.
Used for testing.
| EventLoop& eventloop ()
| eventloop |
Get a reference to the main timer list
| bool status (string& reason)
| status |
[const]
Get the status of the NextHopResolver
Parameters:
| reason | the human-readable reason for any failure |
Returns: false if NextHopResolver has suffered a fatal error, true otherwise
