1 | Building FRR on FreeBSD 9 from Git Source |
2 | ========================================= | |
3 | ||
4 | FreeBSD 9 restrictions: | |
5 | ----------------------- | |
6 | ||
7 | - MPLS is not supported on `FreeBSD`. MPLS requires a Linux Kernel | |
8 | (4.5 or higher). LDP can be built, but may have limited use | |
9 | without MPLS | |
10 | ||
11 | Install required packages | |
12 | ------------------------- | |
13 | ||
14 | Add packages: | |

15 | (Allow the install of the package managment tool if this is first package |
16 | install and asked) | |

17 | |
18 | pkg install -y git autoconf automake libtool gmake gawk \ | |
ae32b152 MW |
19 | pkgconf texinfo json-c bison flex py27-pytest c-ares \ |
20 | python3 | |

22 | Make sure there is no /usr/bin/flex preinstalled (and use the newly |
23 | installed in /usr/local/bin): | |
24 | (FreeBSD frequently provides a older flex as part of the base OS which | |
25 | takes preference in path) | |
26 | ||
27 | rm -f /usr/bin/flex | |

29 | For building with clang (instead of gcc), upgrade clang from 3.4 default to 3.6 *This is needed to build FreeBSD packages as well - for packages clang is default* (Clang 3.4 as shipped with FreeBSD 9 crashes during compile) |
30 | ||
31 | pkg install clang36 | |
32 | pkg delete clang34 | |
33 | mv /usr/bin/clang /usr/bin/clang34 | |
34 | ln -s /usr/local/bin/clang36 /usr/bin/clang | |

36 | Get FRR, compile it and install it (from Git) |

39 | **This assumes you want to build and install FRR from source and not |
40 | using any packages** | |

42 | ### Add frr group and user | |
43 | ||

44 | pw groupadd frr -g 101 |
45 | pw groupadd frrvty -g 102 | |
46 | pw adduser frr -g 101 -u 101 -G 102 -c "FRR suite" \ | |
47 | -d /usr/local/etc/frr -s /usr/sbin/nologin | |
48 | ||
49 | (You may prefer different options on configure statement. These are just | |
50 | an example) | |

95 | ### Enable IP & IPv6 forwarding | |
96 | ||
97 | Add the following lines to the end of `/etc/sysctl.conf`: | |

99 | # Routing: We need to forward packets |
100 | net.inet.ip.forwarding=1 | |
101 | net.inet6.ip6.forwarding=1 | |

102 | |
103 | **Reboot** or use `sysctl` to apply the same config to the running system |
