* bgpd: Move sticky, default_gw, router_flag into a single flags variableDonatas Abraitis2024-07-041-5/+3
| | | | | | | | Instead of using 3 uint8_t variables under struct attr, let's use a single uint8_t as the flags. Saving 2-bytes. Not a big deal, but it's even easier to track EVPN-related flags/variables. Signed-off-by: Donatas Abraitis <donatas@opensourcerouting.org>

* bgpd: support for DF election in EVPN-MHAnuradha Karuppiah2020-10-261-0/+1
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | DF (Designated forwarder) election is used for picking a single BUM-traffic forwarded per-ES. RFC7432 specifies a mechanism called service carving for DF election. However that mechanism has many disadvantages - 1. LBs poorly. 2. Doesn't allow for a controlled failover needed in upgrade scenarios. 3. Not easy to hw accelerate. To fix the poor performance of service carving alternate DF mechanisms have been proposed via the following drafts - draft-ietf-bess-evpn-df-election-framework draft-ietf-bess-evpn-pref-df This commit adds support for the pref-df election mechanism which is used as the default. Other mechanisms including service-carving may be added later. In this mechanism one switch on an ES is elected as DF based on the preference value; higher preference wins with IP address acting as the tie-breaker (lower-IP wins if pref value is the same).

* bgpd: extended-community and attrs for MAC-IP SYNC route handlingAnuradha Karuppiah2020-08-051-1/+2
| | | | | | | | | | | | | | | A new proxy flag has been added to the already existing NA extended community to allow proxy advertisment of a local host by a VTEP that is yet to indpendently establish local reachability. Reference: draft-rbickhart-evpn-ip-mac-proxy-adv The extendend mac-mobility sequence number needs to be synced across the ES peers. However we cannot let a ES-peer path win over a local path on the same ES. To accomplish that some parameters such as the MM seq number are bubbled up from the non-best path to the local path. This mechanism is explained further in the path-selection patch. Signed-off-by: Anuradha Karuppiah <anuradhak@cumulusnetworks.com>
* bgpd: attr changes for EAD routesAnuradha Karuppiah2020-08-051-20/+1
| | | | | | | | | | | | Add ESI as an inline attribute field along with the other EVPN attributes. This may be re-worked when the rest of the EVPN attributes find a new home. Some cleanup has been done to get rid of stale/unused references to ESI. And also to consolidate duplicate definitions of ES ID types.

| | | | | | | | | | | | | | | | | | A route where ESI, GW IP, MAC and Label are all zero at the same time SHOULD be treat-as-withdraw. Invalid MAC addresses are broadcast or multicast MAC addresses. The route MUST be treat-as-withdraw in case of an invalid MAC address. As FRR support Ethernet NVO Tunnels only. Route will be withdrawn when ESI, GW IP and MAC are zero or Invalid MAC Test cases: 1) ET-5 route with valid RMAC extended community 2) ET-5 route no RMAC extended community 3) ET-5 route with Multicast MAC in RMAC extended community 4) ET-5 route with Broadcast MAC in RMAC extended community Signed-off-by: Kishore Aramalla <karamalla@vmware.com>

Set R-bit in EVPN NA if a given router is default gateway or there is a local router attached, which can be determine based on local neighbor entry. Implement BGP ext community attribute to generate and parse R-bit and pass along zebra to program neigh entry in kernel. Upon receiving MAC/IP update with community type 0x06 and sub_type 0x08, pass the R-bit to zebra to program neigh entry. Set NTF_ROUTER in neigh entry and inform kernel to do proxy NA for EVPN.

* bgpd: add basic support for ETI and ESI for BGP EVPNVincent Bernat2018-04-091-0/+1
| | | | | | | | | | | Ethernet Tag ID (ETI) is part of the prefix. It cannot just be ignored as it needs to be used when checking for prefix uniqueness. Moreover, when using Quagga as a route reflector, we need to keep its value. Therefore, we correctly parse and encode it. We also parse ESI. While not part of the prefix, it needs to be reflected correctly by Quagga. Signed-off-by: Vincent Bernat <vincent@bernat.im>

ESI stands for the ethernet segment identifier, and must be entered in following format: 00:11:22:33:44:55:66:77:88:99. gwip stands for the gateway IP address contained in RT5 message.

* bgpd: handling EVPN Route Type 5 NLRI messagePhilippe Guibert2017-02-141-0/+6
| | | | | | | | | | | | | | This patch introduces code to receive a NLRI message with route type 5, as defined in draft-ietf-bess-evpn-prefix-advertisement-02. It It increases the number of parameters to extract from the NLRI and to store into bgp extra information structure. Those parameters are the ESI (ethernet segment identifier), the gateway IP Address (which acts like nexthop attribute but is contained inside the NLRI itself) and the ethernet tag identifier ( that acts for the VXLan Identifier) This patch updates bgp_update() and bgp_withdraw() api, and then does the necessary adapations for rfapi.
