* | lib,zebra,bgpd,staticd: use label code to store VNI infoStephen Worley2023-02-141-2/+31
|/ | | | | | | | | | | | | Use the already existing mpls label code to store VNI info for vxlan. VNI's are defined as labels just like mpls, we should be using the same code for both. This patch is the first part of that. Next we will need to abstract the label code to not be so mpls specific. Currently in this, we are just treating VXLAN as a label type and storing it that way.

* lib, zebra: Add SR-TE policy infrastructure to zebraSebastien Merle2020-08-071-0/+1
| | | | | | | | | | | | | | | | | | | | For the sake of Segment Routing (SR) and Traffic Engineering (TE) Policies there's a need for additional infrastructure within zebra. The infrastructure in this PR is supposed to manage such policies in terms of installing binding SIDs and LSPs. Also it is capable of managing MPLS labels using the label manager, keeping track of nexthops (for resolving labels) and notifying interested parties about changes of a policy/LSP state. Further it enables a route map mechanism for BGP and SR-TE colors such that learned BGP routes can be mapped onto SR-TE Policies. This PR does not introduce any usable features by now, it is just infrastructure for other upcoming PRs which will introduce 'pathd', a new SR-TE daemon.

| | | | | | | | | | | | | | | | | | | | | | This is an implementation of the IS-IS SR draft [1] for FRR. The following features are supported: * IPv4 and IPv6 Prefix-SIDs; * IPv4 and IPv6 Adj-SIDs and LAN-Adj-SIDs; * Index and absolute labels; * The no-php and explicit-null Prefix-SID flags; * Full integration with the Label Manager.

* lib, zebra: support label chunk requests for SRGBEmanuele Di Pascale2019-07-101-0/+1
| | | | | | | | | | | | | | | | For SRGB, we need to support chunk requests starting at a specific point in the label space, rather than just asking for any sufficiently large chunk. To this purpose, we extend the label manager api to request a chunk with a base value; if the base is set to 0, the label manager will behave as it currently does, i.e. fetching the first free chunk big enough to satisfy the request. update all the existing calls to get chunks from the label manager so that they use MPLS_LABEL_BASE_ANY as the base for the requested chunk Signed-off-by: Emanuele Di Pascale <emanuele@voltanet.io>

* | bgpd: Install SAFI_LABELED_UNICAST routes in SAFI_UNICAST tableDaniel Walton2017-06-161-2/+7
|/ | | | | | | | | | | | | | | | | | | | | Signed-off-by: Daniel Walton <dwalton@cumulusnetworks.com> - All ipv4 labeled-unicast routes are now installed in the ipv4 unicast table. This allows us to do things like take routes from an ipv4 unicast peer, allocate a label for them and TX them to a ipv4 labeled-unicast peer. We can do the opposite where we take routes from a labeled-unicast peer, remove the label and advertise them to an ipv4 unicast peer. - Multipath over a labeled route and non-labeled route is not allowed. - You cannot activate a peer for both 'ipv4 unicast' and 'ipv4 labeled-unicast' - The 'tag' variable was overloaded for zebra's route tag feature as well as the mpls label. I added a 'mpls_label_t mpls' variable to avoid this. This is much cleaner but resulted in touching a lot of code.

* bgpd, lib, zebra: Implement handling of BGP-Prefix-SID label IndexVivek Venkatraman2017-04-061-0/+5
| | | | | | | | | | | | | | | | Implement BGP Prefix-SID IETF draft to be able to signal a labeled-unicast prefix with a label index (segment ID). This makes it easier to deploy global MPLS labels with BGP, even without other aspects of Segment Routing implemented. This patch implements the handling of the BGP-Prefix-SID Label Index attribute. When received from a peer and the index is acceptable, the local label is picked up from the SRGB and is programmed as the incoming label as well as advertised to peers. If the index is not acceptable, no local label is assigned. The outgoing label will always be the one advertised by the downstream neighbor.

* Implement generic label managerßingen2017-03-201-0/+2
| | | | | | | | | | | | | | | | | | | | | | | | | Label Manager allows to share MPLS label space among different daemons. Each daemon can request a chunk of consecutive labels and release it if it doesn't need them anymore. Label Manager stores the daemon protocol and instance to identify the owner client. It uses them to perform garbage collection, releasing all label chunks from a client when it gets disconnected or reconnected. Additionally, every client can request that the chunk is never garbage collected. In that case client has the responsibility to release non-used labels. Zebra can host the label manager itself (if no -l param is provided) or connect to an external one using zserv/zclient (providing its address with -l param). Client code is in lib/zclient.c, but currently only LDP is using it. TODO: Allow for custom ranges requests, i.e., specify the start label besides the chunk. TODO: Release labels from LDP.
