zebra's Introduction

coreswitch

coreswitch is an open soruce project for EPC (Evolved Packet Core) of LTE and 5G infrastructure. Right now we are implementing MME (Mobility Management Entity). Other component will be implemented later on.

Supported Platform

Right now only Ubuntu 18.04 is supported.

Build

To build the system. ASN1 handling C library needs to be built.

$ cd coreswitch/pkg/s1ap/asn1
$ make lib
$ sudo make install

After this

$ go get github.com/coreswitch/coreswitch/cmd/mmed

will build mmed.

Run

Just simply execute mmed will start MME handling on all of interfaces.

$ mmed

no go mod to keep api stable

go get cmd will fail like, this is the grpc api problem, but could be addressed by go mod

Netlink route delete messages cannot be received when interface's VRF changed

When a VLAN interface which belongs to a VRF moves to another VRF, the static routes on the interface at the first VRF are automatically deleted, however, netlink route delete messages for those routes cannot be received.

I used ip monitor command to monitor netlink messages, but any netlink route delete messages for those routes couldn't be received, it probably means that Linux kernel doesn't send netlink route delete messages for those routes.

This problem can be appeared at both the latest version of ribd/openconfigd pair and the first commit version of them as well.

How to reproduce

Use the config below and boot ribd
Start monitoring netlink route messages using ip monitor command
ip monitor route
On openconfigd cli, chaneg the vlan100's belonging VRF from default VRF to vrf1, and commit.
set interfaces interface vlan100 vrf vrf100
At this point, two routes; 172.16.1.0/24 and 172.16.2.0/24 are properly deleted from linux kernel routing table, however, netlink route delete messages for theses routes are not received.
