2019-11-26fib: Table ReplaceNeale Ranns1-2/+0
Type: feature from the API doc, a table replace is: " The use-case is that, for some unspecified reason, the control plane has a very different set of entries it wants in the table than VPP currently has. The CP would thus like to 'replace' VPP's current table only by specifying what the new set of entries shall be, i.e. it is not going to delete anything that already eixts. the CP delcartes the start of this procedure with this begin_replace API Call, and when it has populated all the entries it wants, it calls the below end_replace API. From this point on it is of coursce free to add and delete entries as usual. The underlying mechanism by which VPP implements this replace is purposefully left unspecified. " In the FIB, the algorithm is implemented using mark and sweep. Algorithm goes: 1) replace_begin: this marks all the entries in that table as 'stale' 2) download all the entries that should be in this table - this clears the stale flag on those entries 3) signal the table converged: ip_table_replace_end - this removes all entries that are still stale this procedure can be used when an agent first connects to VPP, as an alternative to dump and diff state reconciliation.

2019-06-03ARP: add feature arcNeale Ranns1-0/+11
- arp-input, registered with the ethernet protocol dispatcher, performs basic checks and starts the arc - arp-reply; first feature on the arc replies to requests and learns from responses (no functional change) - arp-proxy; checks against the proxy DB arp-reply and arp-proxy are enabled when the interface is appropriately configured.
