 Quagga needs to be installed separatly. It is assume to be configured 
 like the standard Ubuntu Packages:
 
 - Binaries in /usr/lib/quagga

 - Running under user quagga, group quagga
 - vtygroup: quaggavty

+#### Manual Quagga build
+
+If you prefer to manually build Quagga, then use the following suggested config:
+
+       ./configure \
+               --prefix=/usr \
+               --localstatedir=/var/run/quagga \
+               --sbindir=/usr/lib/quagga \
+               --sysconfdir=/etc/quagga \
+               --enable-vtysh \
+               --enable-pimd \
+               --enable-multipath=64 \
+               --enable-user=quagga \
+               --enable-group=quagga \
+               --enable-vty-group=quaggavty \
+               --with-pkg-extra-version=-my-manual-build
+
+And create Quagga User and Quaggavty group as follows:
+
+       addgroup --system --gid 92 quagga
+       addgroup --system --gid 85 quaggavty
+       usermod -G quaggavty quagga
+       adduser --system --ingroup quagga --home /var/run/quagga/ \
+          --gecos "Quagga routing suite" --shell /bin/false quagga
