  Recent simulations and observations have shown large scale filaments in the
cosmic web connecting nodes, with accreting materials (baryonic and dark
matter) flowing through them. Current high sensitivity observations also show
that the propagation of shocks through filaments can heat them up, and make
filaments visible between two or more galaxy clusters or around massive
clusters, based on optical and/or X-ray observations. We are reporting here the
special case of the cluster A3017 associated with a hot filament. The
temperature of the filament is 3.4$^{-0.77}_{+1.30}$ ~keV and its length is
$\sim$ 1 Mpc. We have analysed its archival {\it Chandra} data and report
various properties. We also analysed GMRT 235/610 MHz radio data. Radio
observations have revealed symmetric two-sided lobes which fill cavities in the
A3017 cluster core region, associated with central AGN. In the radio map, we
also noticed a peculiar linear vertical radio structure in the X-ray filament
region which might be associated with a cosmic filament shock. This radio
structure could be a radio phoenix or old plasma where an old relativistic
population is re-accelerated by shock propagation. Finally we put an upper
limit on the radio luminosity of the filament region.
